One fourth the cube of x

Look at triangle wxy what is the length (in centimeters) of the side wy of the triangle?

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.

What is the solution of the equation? 35√(x+2)3+3=27
