Answer:
The graph in the attached figure
Step-by-step explanation:
we have
This is a vertical parabola open upward
The vertex is a minimum
step 1
Find the x-intercepts
The x-intercepts are the values of x when the value of the function is equal to zero
For f(x)=0
Factor x
The x-intercepts are (0,0) and (-4,0)
step 2
Find the y-intercept
The y-intercept is the values of the function when the value of x is equal to zero
For x=0
The y-intercept is (0,0)
step 3
Find the vertex
Convert the equation into vertex form
Complete the square
Rewrite as perfect squares
The vertex is the point (-2,-4)
therefore
using a graphing a graphing tool
The graph in the attached figure
