Question

Which is f(5) for the function –2x2 + 2x - 3?

Answer 1

f(x)=-13

Explanation:

-2x2+2x-3

-2(5)*2+2(5)-3

-10*2+10-3

-20+7=-13

I hope this helps!

Answer 2

The value of f(5) is -43

Explanation:

`f(x)=-2x^2 + 2x - 3`

To find f(5) we plug in 5 for x in the given equation f(x)

Replace all x by 5

`f(x)=-2x^2 + 2x - 3`

`f(5)=-2(5)^2 + 2(5) - 3`

`f(5)=-2(25) + 10 - 3`

`f(5)=-50+ 10- 3=-43`

The value of f(5) is -43
