A third degree polynomial equation (a cubic equation) is of the form p(x) = c3x 3 + c2x 2 + c1x + c0, where x and the four coefficients are integers for this exercise. Suppose the values of the coefficients c0, c1, c2, and c3have been loaded into registers $t0, $t1, $t2, and $t3, respectively. Suppose the value of x is in $t7. Write the MIPS32 instructions that would evaluate this polynomial, placing the result in $t9.

For the following exercises, use the graphs to write a polynomial function of least degree.
