The equivalent value of the function [tex]\rm f(x) = -2x^2 -3x + 5[/tex] if x = -3 is -4.
Function; [tex]\rm f(x) = -2x^2 -3x + 5[/tex] for the input value –3.
What are the x-intercepts of the function f(x)?
To determine the value of the function following all the steps given below.
For x = -3, we will have to substitute x = -3 into the expression to have:
Then,
The value of f(x) when x is -3 is,
[tex]\rm f(-3) = -2(-3)^2 -3(-3) + 5\\\\ f(-3) = -2(9) + 9 + 5 \\\\f(-3) = -18 + 14 \\\\\f(-3) = -4 [/tex]
Hence, The equivalent value of the function [tex]\rm f(x) = -2x^2 -3x + 5[/tex] if x = -3 is -4.
