Question

PLEASE HELP:

For the polynomial, list each real zero and its multiplicity. Determine whether the graph crosses or touches the x-axis at each x -intercept.

f(x) = 4(x - 7)(x + 4)4

Answer 1

\(\bf f(x) = 4(x - 7)(x + 4)^4\\
0 =4(x - 7)(x + 4)^4\)

so what values does "x" have?

Answer 2

keep in mind that \(\bf 0 =4(x - 7)(x + 4)^4 \implies 0 =4(x - 7)(x + 4)(x + 4)(x + 4)(x + 4)\)

Answer 3

Oh, that was a 4th power x_x
