-4, 4 3 4 crosses touches

Step-by-step explanation:

f(x) = -4(x - 4)(x² - 16)³

 0  = -4(x - 4)(x² - 16)³

0 = -4               0 = x - 4          0 = (x² - 16)³

not valid             x = 4              0 = [(x - 4)(x + 4)]³

                                                0 = (x - 4)(x + 4)(x - 4)(x + 4)(x - 4)(x + 4)

                                                    x = 4,  x = -4, x = 4, x = -4, x = 4, x = -4

Zeroes: x = -4 multiplicity of 3 and x = 4 multiplicity of 4

odd multiplicity crosses, even multiplicity touches

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1
