To multiply a function by another function, multiply their outputs. For example, if f (x) = 2x and g(x) = x + 1, then fg(3) = f (3)×g(3) = 6×4 = 24. fg(x) = 2x(x + 1) = 2x2 + x.

Can a function be multiplied?
When you multiply two functions together, you’ll get a third function as the result, and that third function will be the product of the two original functions. For example, if you multiply f(x) and g(x), their product will be h(x)=fg(x), or h(x)=f(x)g(x).
What happens when you multiply a function by 2?
We can also stretch and shrink the graph of a function. To stretch or shrink the graph in the y direction, multiply or divide the output by a constant. 2f (x) is stretched in the y direction by a factor of 2, and f (x) is shrunk in the y direction by a factor of 2 (or stretched by a factor of ).
How do you multiply in an Excel formula?

How do you find the profit function?
To obtain the profit function, subtract costs from revenue.
How do you multiply fractions with functions?
To multiply rational expressions:
- Completely factor all numerators and denominators.
- Reduce all common factors.
- Either multiply the denominators and numerators or leave the answer in factored form.
What does 7x mean in math?
7x, or seven times in multiplication.
What is f/g x?
Composition means that you can plug g(x) into f (x). This is written as “( f o g)(x)“, which is pronounced as “f-compose-g of x”. And “( f o g)(x)” means ” f (g(x))”. That is, you plug something in for x, then you plug that value into g, simplify, and then plug the result into f.
Which math function is used to multiply itself 4 times Java?
pow() is an built-in method in Java Math class and is used to calculate the power of a given number. The power of a number refers to how many times to multiply the number with itself.
What does multiplying a function by 3 do?
We have multiplied x by 3. This should affect the graph horizontally.Therefore the graph if this parabola will be taller/thinner than y = x2. Multiplying x by a number greater than 1 creates a horizontal compression, which looks like a vertical stretch.
How do you solve this math problem?

- Read carefully, understand, and identify the type of problem.
- Draw and review your problem.
- Develop the plan to solve it.
- Solve the problem.
What is the product of 3 5×2 5?
Multiplying Fractions
You can find the product of two or several fractions. Here are instructions on finding the product of fractions. Start with fractions for which you need to find the product. In this example, we will multiply the fractions 4/6 and 3/5.
How do you multiply exponents?
When you’re multiplying exponents, use the first rule: add powers together when multiplying like bases. 52 × 56 = ? The bases of the equation stay the same, and the values of the exponents get added together. Adding the exponents together is just a shortcut to the answer.
What is the profit equation?
This simplest profit formula when calculating profit for one item is: profit = price – cost. Calculating profit for a higher quantity of items involves deducting direct costs, such as materials and labour and indirect costs (also known as overheads) from sales.
How do I calculate marginal profit?
Once you know the marginal cost and the marginal revenue, you can get marginal profit with the following simple formula: Marginal Profit = Marginal Revenue – Marginal Cost.
What is profit function example?
Profit function = Revenue function – Cost function = R( ) – C( ) = (500 ) – (175 +150 ) = 500 – 175 – 150 = 325 -150 4. A company produces and sells a product and fixed costs of the company are Rs.25 per unit, and sells the product at Rs. 50 per unit.
