Answer:
Part 1) The y-intercept is the point
Part 2) The x-intercepts are the points
Step-by-step explanation:
we have
This is a vertical parabola open upward
step 1
Find the y-intercept
we know that
The y-intercept is the value of y when the value of x is equal to zero
so
For x=0
The y-intercept is the point (0,-3)
step 2
Find the x-intercepts
we know that
The x-intercept is the value of x when the value of y is equal to zero
so
For y=0
solve for x
Adds 3 both sides
take square root both sides
so
The x-intercepts are the points
