At which root does the graph of f(x) = (x + 4)6(x + 7)5 cross the x axis?
a. –7
b. –4
c. 4
d. 7

When graphing polynomial functions you need to look at the power.

If the power is even, the graph will TOUCH the x axis but not pass through the axis. If the power is odd, the graph will pass through the axis.
at x = -4 the power is even so the graph TOUCHES.
at x = -7 the power is odd so the graph CROSSES.

11/2.2 = 5 inches for the length 8.5/2.2= 3.86 inches for the width
