46. use matlab to plot the polynomials y = 3x 4 − 6x 3 + 8x 2 + 4x + 90 and z = 3x 3 + 5x 2 − 8x + 70 over the interval −3 ≤ x ≤ 3. properly label the plot and each curve. the variables y and z represent current in milliamperes; the variable x represents voltage in volts.

Which of the following is the correct equation for this function? a. y= (x+4)(x+2) b. y=x^2+ 3x – 2 c. y+ 2 = – 2(x+3)^2 d. y+ 2 = 2(x+3)^2
