F(3) = 4x2 + 5x - 3
g(x) = 4x3 - 3x² + 5
Find (f +g)(x).

Janet is rolling a number cube with the numbers one through six she record the numbers after each row if she rolls of keep 48 times how many times should she expect to roll a 4

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
