Question

If f(x)=−2(x+7), then what is f(−10)?

Answer 1

`→f(x) = - 2(x + 7) \\ f( - 10) = - 2( - 10 + 7) \\ f( - 10) =( - 2) * ( - 3) \\ \boxed{f( - 10) = 6}✓`

• f(-10)=6 is the right answer.

Answer 2

f(-10) = 6

Explanation:

f(x) is simply just the name of the function. x will be your dependent variable that you'll use to plug into the equation.

Since they want you to find f(-10), you'll then plug -10 in where x was and solve.

f(-10) = -2((-10)+7)

f(-10) = -2(-3)

f(-10) = 6
