Question

Evaluate the function rule for the given value. f(x) = 3x for x = –5

Answer 1

this is the answer -15

Answer 2

Answer:

value of function for x = -5 is -15

Step-by-step explanation:

Given the function:

$f(x) = 3x$

We have to find the value of function for x = -5

Substitute the value of x = -5 in [1] we get;

$f(x) = 3(-5)$

Simplify:

$f(x) =-15$

therefore, the value of function for x = -5 is -15
