Excellent, hardworking and passionate Math Tutor
f(x) = a(x-h)+k
a is vertical compression
h is horozontal shift
k is vertical shift
a. y = 12(x+1) - 4
b. Slope m = 12
c. Vertical intercept
x = 0 g(x) = 12(0+1) - 4 = 12-4 =8

What specifically are we troubled on here? Do you need help with how to start? Think about what each of these transformations mean for a graph of a function. What is vertical compression? Which variable is affected by a shift left and in which way? What about shifting down? Which variable is affected by that shift and how? I'd like to answer this question, but I'd rather see where the confusion is before I start.03/28/21
