Vertical stretch:
Suppose, we are given any function f(x)
and it is asked to vertically stretch graph of f(x) by 'a' units
Vertical stretch means stretching y-value
and f(x) is y-value
so, we multiply 'a' to f(x)
so, our function will become
now, we are given
The graph of function g(x) is a vertical stretch of the graph of function f(x) by a factor of 10.
It means that parent function is f(x)
and new function becomes g(x)
and it is stretching vertically by 10 units
so, we can write as
............Answer
Answer:
-2
Step-by-step explanation:

Therefore, the average rate of change over the interval [-4,-1] is -2.
Answer:
The vertex is at (-8, -56).
Step-by-step explanation:
x^2+16x+8
= (x + 8)^2 - 64 + 8
= (x + 8) - 56.
The vertex is at (-8, -56).
