Find the y coordinate corresponding to each x-coordinate if the functions are f(x) = -2x -5 and g(x) = -3.75 (2.5)x

How is working backward similar to solving an equation?

What’s the answer ? use the picture to see the problem

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.
