Determine if the expression -1 is a polynomial or not. If it is a polynomial, state the type and degree of the polynomial.

For the function, f(x) = -5x 2, find f(-4).

What is f(3) for the quadratic functionf(x)=2x2 + x – 12? f -3g 3h 6i. 9

The table below represents a linear function f(x) and the equation represents a function g(x): x f(x) −1 −5 0 −1 1 3 g(x) g(x) = 2x − 7 part a: write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points) part b: which function has a greater y-intercept? justify your answer. (4 points)
