Answer:
The Answer is: (-6, 11); (3, 5); (15, -3); (-12, 15)
Step-by-step explanation:
f(-6) = -2/3(-6) + 7 = 12/3 + 7 = 4 + 7 = 11
f(3) = -6/3 + 7 = -2 + 7 = 5
f(15) = -30/3 + 7 = -10 + 7 = -3
f(-12) = -2/3(-12) + 7 = 24/3 + 7 = 8 + 7 = 15
To find the -12, you have to solve for x:
-2/3x + 7 = 15
-2/3x = 15 - 7
-2/3x = 8
x = -3/2 * 8 = -24/2 = -12
Then to prove the number, find f(-12) = 15
