82.) a varies directly as b and inversely as the square of c, and a=10, when b=8 and c=2. Find a when b=20 and c=5. i also give brainliest UwU

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.
