# Which is f(5) for the function -2x^{2} + 2x - 3?

-107, -63, -43, -37

**Solution:**

Given, f(x) = -2x^{2} + 2x - 3

We have to find f(5)

Put the value x = 5 in the given function.

f(5) = -2(5)^{2} + 2(5) - 3

= -2(25) + 10 - 3

= -50 + 10 - 3

= 10 - 53

= - 43

Therefore, f(5) = -43.

**Example:**

Which is f(2) for the function 2x^{2} + 4x - 5?

**Solution:**

Given, f(x) = 2x^{2} + 4x - 5

We have to find f(2)

Put the value x = 5 in the given function.

f(2) = 2(2)^{2} + 4(2) - 5

= 2(4) + 8 - 5

= 8 + 8 - 5

= 16 - 5

= 11

Therefore, f(2) = 11.

## Which is f(5) for the function -2x^{2} + 2x - 3?

**Summary:**

f(5) for the function -2x^{2} + 2x - 3 is -43.
