Question

The table below represents a linear function f(x), and the equation represents a function g(x): X) -1, 0, 1 F(x) -5, -1, 3 G(x)=2x+8

Part A. Wrote a sentence to compare the slope of the two functions and shows the steps you used to determine the slope of f(x) and g(x)

Part B which functions has greater y-intercept. Justify

Answer 1

f(x) = 4x - 1. You can get this by using the slope formula and then point-slope form.

1. The slope of f(x) is twice as steep as that of g(x).

2. The y intercept of g(x) is much greater than that of f(x) because 8>-1
