i worked out the problem
The value of b would be 47
Answer:
First, let's write the general transformations:
a) A vertical stretch by a factor of 3.
f(x) ---> 3*f(x)
b) A reflection in the y-axis.
3*f(x) ----> 3*f(-x)
c) A translation of 2 units to the left.
3*f(-x) ----> 3*f(-x + 2)
then we know that:
g(x) = 3*f(-x + 2)
and f(x) = x^2 - x + 1
Then:
g(x) = 3*( (-x + 2)^2 - (-x + 2) + 1)
g(x) = 3*( x^2 - 4*x + 4 +x - 2 + 1) = 3*(x^2 - 3*x + 3)
g(x) = 3*x^2 - 9*x - 9
