Answer:
Part 1) The turning point is (5,3)
Part 2) The y-intercept is the point (0,28)
Part 3) The graph don't cross the x-axes
Part 4) The graph in the attached figure
Step-by-step explanation:
Part 1) State the turning point
we know that
A <u><em>turning point</em></u> is a point of the graph where the graph changes from increasing to decreasing (rising to falling) or decreasing to increasing (falling to rising)
we have
This is the equation of a vertical parabola written in vertex form
The parabola open upward
The vertex represent a minimum
The vertex is the point (5,3)
therefore
The turning point is (5,3)
Part 2) 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 (0,28)
Part 3) Find the x-intercepts of the quadratic equation
we know that
The x-intercept is the value of x when the value of y is equal to zero
so
For y=0
Remember that
so
The graph don't cross the x-axes
Part 4) The graph in the attached figure
