Question

14. F(x)= 3x - 12 x=(-2,-3,4)Y=

Answer 1

x = -2, y = -18

x = -3, y = -21

x = 4, y = 0

Step-by-step explanation

We want to find y for

f(x) = 3x - 12

when x = -2, -3 and 4

y and f(x) represent the same thing, so we have to just find f(x).

WHEN x = -2:

f(x) = 3(-2) - 12

f(x) = -6 - 12

f(x) = -18

WHEN x = -3:

f(x) = 3(-3) - 12

f(x) = -9 - 12

f(x) = -21

WHEN x = -4:

f(x) = 3(4) - 12

f(x) = 12 - 12

f(x) = 0
