If f(x) = 2x2 + 3 and g(x) = x2 – 7, find (f + g)(x).

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)

If y varies directly as x2 and y=6 when x=6, find the constant of variation.

Me. i can't figure out this question. give an explanation too. .
