The acceleration of an object due to gravity is 32 feet per second squared.what is acceleration due to gravity in inches per second squared?

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.

For a function f(x), a) if f(7) = 22 then f^-1(22) = b) f^-1(f(c)) =
