Question

Let the function f be defined by y = f(x), where x and f(x) are real numbers. Find the following:() = 4―10

Answer 1

Given

`f(x)=4x-10`

To find the value of f(-7).

Step-by-step explanation:

It is given that,

`f(x)=4x-10`

Then, for x=-7.

`\begin{gathered} f(-7)=4(-7)-10 \\ =-28-10 \\ =-38 \end{gathered}`

Hence, f(-7)=-38.
