The linear polynomial q(x)=−4x+8 is to be studied.
a. (i) State the meaning of a zero of a polynomial.
b. (ii) Verify that x=2 is a zero of q(x).
c. (iii) Draw the graph of the line y=q(x) on your graph paper and clearly mark its zero, x-intercept, and y-intercept. Write the coordinates of these points.
