Question

Evaluate the function f(x)=3x+4 at x=-6

Answer 1

-14

Explanation:

f(x)=3x+4

Let x=-6

f(-6) = 3(-6) +4

= -18+4

= -14

Answer 2

Since we know what x equals, we can substitute and solve. Remember to use PEMDAS when solving.

f(x) = 3x + 4

f(-6) = 3(-6) + 5

f(-6) = -18 + 5

f(-6) = -13

Best of Luck!
