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.

Combined megan and kelly worked 60 hours.kelly worked twice as many hours as megan.how many hours did they each worked?

Is appreciated! graph the functions and approximate an x-value in which the exponential function surpasses the polynomial function. f(x) = 4^xg(x) = 4x^2options: x = -1x = 0x = 1x = 2

Which two transformations are applied to pentagon abcde to create a'b'c'd'e'? (4 points) translated according to the rule (x, y) ? (x + 8, y + 2) and reflected across the x-axis translated according to the rule (x, y) ? (x + 2, y + 8) and reflected across the y-axis translated according to the rule (x, y) ? (x + 8, y + 2) and reflected across the y-axis translated according to the rule (x, y) ? (x + 2, y + 8) and reflected across the x-axis
