Question

Evaluate f(x) = 5x -8 when x = -3,0, and 4.​

Answer 1

Explanation:

Substitute x with the number given, for example, f(-3) = 5*-3 -8, so

5*-3 is -15 minus 8 is -23. For 0 the equation would be f(0) = 5*0 -8, so

5*0 is 0 minus 8 is -8. For 4 the equation would be f(4) = 5*4 -8, so

5*4 is 20 minus 8 is equal to 12.

Answers:

f(-3) = -23

f(0) = -8

f(4) = 12
