The parent function of P(x) = 3(x+2)5+96 is y=x5, which passes through the points (—2,—32), (—1,—1), (0,0), (1,1), and (2,32).
P(x)=3(c+2)5+96 is the graph of y=x5 reflected across the x-axis, vertically stretched by 3, and translated left 2 units and up 96 units. Multiplying the y-coordinates of the points on y=x5by3 to reflect them across the x-axis and vertically stretch them by 3 gives the points (-2,96), (-1,3), (0,0), (1, -3), and (2,-96). Translating the points left 2 units and up 96 units then gives the points (-4, 192), (-3,99), (-2,96), (-1,93), and (0,0).
The x-intercept of P(x) is when P(x)=0 which we already know is at (0,0). Note that P(x) can have only one x-intercept since y=x5 has only one x-intercept.
The y-intercept is when x=0 which we know is at (0,0).
Plot the points and then connect them with a smooth curve. Label the coordinates at the interceps in your graph.
See the explanation for the graph. To make the graph, reflect the graph ot y=x5 across the x-axis, vertically stretch it by 2, and then translate it left 2 mits and up 96 units. Label the intercept at (0,0).
