Answer:
The vertex of the function is at (1,–25)
The graph is negative on the entire interval -4 < x < 6
Step-by-step explanation:
we have
This is a vertical parabola open upward
The vertex is a minimum
using a graphing tool
see the attached figure
The vertex is the point (1,-25)
The x-intercepts or roots of the quadratic function are x=-4, x=6
The graph is increasing on the interval x > 1
The graph is decreasing on the interval x < 1
The graph is positive on two intervals ,where x < -4 and x > 6
The graph is negative on the entire interval -4 < x < 6
therefore
The statements that are true are
The vertex of the function is at (1,–25)
The graph is negative on the entire interval -4 < x < 6
