Aight mate can someone help me lol

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

Use the quadratic function to predict f(x) if x equals 8. f(x) = 25x2 − 28x + 585

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.
