F(t)=-t g(t) = 4t - 5 Find f (t) + g(t)

Use composition to determine if (x) or h(x) is the inverse of f(x) for the limited domain x2-1.

What is the axis of symmetry of the function f(x)=-(x+ 9)(x-21)

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.
