Exercise 55 Page 78

The real zeros of a function are x-intercepts of its graph.

two negative real zeros, one positive real zero and two imaginary zeros

Practice makes perfect

Because the degree of the function is 5, it has five zeros. The real zeros of a function are x-intercepts of its graph.

The polynomial function has two x-intercept on the negative side of the x-axis and one x-intercept on the positive side of the x-axis. Therefore, it has two negative real zeros and one positive real zero. The remaining two zeros are the imaginary zeros.
