Expansions and compressions are transformations that change the length or width of the graph of a function.
To graph y = a*f (x)
if a> 1, the graph of y = f (x) is expanded vertically by a factor a.
We have then:
f (x) = 2/5 x ^ 2-2
The function g (x) is a vertical stretch of f (x) by a factor of 2:
g (x) = 2f (x)
g (x) = 2 (2/5 x ^ 2-2)
g (x) = 4/5 x ^ 2-4
Answer:
The equation of g (x) is:
g (x) = 4/5 x ^ 2-4
Answer:
The answer is 0.
Step-by-step explanation:
You are right because the -4 and 4 would be an x - intercept but it's not there on the answer choice. So, go with A. 0 Another explainationor this is (0,9) is the vertex, and the x intercept lies on 0.
Answer:
yes
Step-by-step explanation:
cross-products both equal 180
20(9) = 10(18)
180 = 180
