Answer the following questions

1. f(x) = =x - 3ory =;x-3 a) The input is x and the output is f(x) or y. What is the slope of the function? b) What is the y-intercept of the function? c) What is the x-intercept of the function? d) Graph the function. 2. What is the slope of a horizontal line? 3. Determine whether each function is increasing or decreasing? 3.1 f(x) = 4x + 3 3.2 a(x) = 5 - 2x 3.3 k(x) = -4x +1 3.4 p(x)=x 3.5 q(x) = 4 4.
