Answer:
Option (a) is correct.
The value of given function [tex]f(x)=-5x^2-x+20[/tex] at x = 3 is -28
Step-by-step explanation:
Given : Function [tex]f(x)=-5x^2-x+20[/tex]
We have to find the value of given function at x = 3
Consider the given function [tex]f(x)=-5x^2-x+20[/tex]
Since, we have tof ind the value of function at x = 3
Put x = 3 in given function f(x)
[tex]f(3)=-5(3)^2-(3)+20[/tex]
Simplify, we have,
[tex]f(x)=-45-3+20=-28[/tex]
Thus, the value of given function [tex]f(x)=-5x^2-x+20[/tex] at x = 3 is -28
