Evaluate the function when x=1. f(x)=4x-2. Write the input and output as a set of ordered pairs, and identify the domain and range of the ordered pair. (6 points)
Ordered Pair:
Domain:
Range:
Write an equation of direct variation that passes through the point (9,-1). (4 points)
Write an equation of a line in point-slope form if the slope is -1 and it passes through the point (-3, 5). (4 points)
Write the equation of a line through the point (-2, 1) and perpendicular to 3x+y=1. (4 points)
Write a function rule for the transformation for the graph f(x)=5x.
The graph shifts to the left 4 points, up 2 points, vertically compresses by a factor of 1/2, and reflects in the x-axis. (4 points)
Graph the inequality y<3/2 x+2. (4 points)
