Answer:
g(x) = |x/5|
Step-by-step explanation:
A function is stretched horizontally by a factor of k when x is replaced by x/k.
g(x) = f(x/5)
g(x) = |x/5| . . . . . stretch of absolute value by a factor of 5

Given:
The vertex of a quadratic function is (4,-7).
To find:
The equation of the quadratic function.
Solution:
The vertex form of a quadratic function is:
...(i)
Where a is a constant and (h,k) is vertex.
The vertex is at point (4,-7).
Putting h=4 and k=-7 in (i), we get
The required equation of the quadratic function is where, a is a constant.
Putting a=1, we get
Therefore, the required quadratic function is .
