Given the function ƒ(x) = 8x^2 − 14x − 10, find ƒ(−2).

Answers

Answer:

f(-2)  =  50

Step-by-step explanation:

What f(-2) simply means is that you will substitute -2  in  f(x) = 8x^2 − 14x − 10.

That is wherever you see x you replace it by 2

f(-2)  = 8(-2)²  - 14(-2)   -  10

        =  8(4)   + 28   - 10   (note (-2)² = -2 × -2 =  4.   Also, -14  × -2 = 28)

           = 32   +  28  - 10

          =  60 -10

          =50

Therefore f(-2)   = 50

Answer:

f(- 2) = 50

Step-by-step explanation:

To evaluate f(- 2) substitute x = - 2 into f(x)

f(- 2) = 8(- 2)² - 14(- 2) - 10

       = 8(4) + 28 - 10 = 32 + 28 - 10 = 50
