A. -28

Step-by-step explanation:

Answer 2

Answer:

Option (a) is correct.

The value of given function  $f(x)=-5x^2-x+20$ at x = 3 is -28

Step-by-step explanation:

Given : Function $f(x)=-5x^2-x+20$

We have to find the value of given function at x = 3

Consider the given function  $f(x)=-5x^2-x+20$

Since, we have tof ind the value of function at x = 3

Put x = 3 in given function f(x)

$f(3)=-5(3)^2-(3)+20$

Simplify, we have,

$f(x)=-45-3+20=-28$

Thus,  the value of given function  $f(x)=-5x^2-x+20$ at x = 3 is -28
