2. Identify the x-values for which f(x)>-2
{x|2<x<8}
3. The figure shows the graph of the function y=(x-1)^2-4. Identify the x-values for which the function in increasing.
{x|x>1}
4. Identify the x- and y-intercepts of the graph
X-intercepts: (-1,0) and (3,0)
y-intercepts: (0,-3)
5. a batter hits a baseball into the air at an angle. The height of the ball in feet, is modeled by a quadratic function h(t), where t represents time, measured in seconds. Use the graph of the function to determine which pf the following statements most accurately models the height of the ball 5 seconds after is was hit.
h(5)=75
I hope you have a great day!
