Question

if f(x) = 2x -3 what is the value of f(x) when x is -5?

Answer 1

Answer:

-13    

Step-by-step explanation:

To find the value of f(x) when x is -5, substitute -5 for the x in the equation. Then, simplify:  

$f(x) = 2x-3\\\\f(-5) = 2(-5)-3\\f(-5) = -10-3\\f(-5) = -13$

So, when x is -5, the value of f(x) will be -13.
