The value of f(3), f(-7) and f(-2)+9 are 7, -23 and 1
Given the function f(x) = 3x - 2
f(3) = 3(3) - 2
f(3) = 9 - 2
f(3) = 7
Get f(-7)
f(-7) = 3(-7) - 2
f(-7) = -21-2
f(-7) = -23
Get f(-2)
f(-2) = 3(-2) - 2
f(-2) = -6 - 2
f(-2) =-8
Hence f(-2) + 9 = -8 + 9
f(-2) + 9 = 1
Hence the value of f(3), f(-7) and f(-2)+9 are 7, -23 and 1
