Given the function:

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

Determine the value of the function when the input value is -3.

Solution:

Substitute the input value of -3 to x in the function f(x).

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

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

f(-3) = -2(9) + 9 + 5

f(-3) = -18 + 9 + 5

f(-3) = -4

Final answer:

f(-3) = -4
