In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data:
graph
y = 1/2 x² - 2
Step 02:
appearance of the graph:
we must analyze the graph to find the solution.
1/2 ===> 2
f(x) = a f ( b (x + h)) + k
b = stretch or compression horizontal
b > 1: compression
b < 1: stretch
b = 2 > 1 ===> narrower
The answer is:
The graph will be narrower
