b. find the x-intercept(s).

the x-intercept(s) is/are 0, 3, -5.
(type an integer or a decimal. use a comma to separate answers as needed.)

at which zero(s) does the graph of the function cross the x-axis? select the correct choice below and, if necessary, fill in the answer box to complete your choice.

a. the graph crosses the x-axis at the zero(s) 3, -5.
(type an integer or a decimal. use a comma to separate answers as needed.)
b. there are no zeros at which the graph crosses the x-axis.

at which zero(s) does the graph of the function touch the x-axis and turn around? select the correct choice below and, if necessary, fill in the answer box to complete your choice.

a. the graph touches the x-axis and turns around at the zero(s) 0.
(type an integer or a decimal. use a comma to separate answers as needed.)
b. there are no zeros at which the graph touches the x-axis and turns around.
