Asked by Becky

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.

Ordered Pair:
Domain:
Range:

2. Write an equation of direct variation that passes through the point (9,1).
Answered by Steve
what? Can't plug in a value for x and evaluate? For example,

f(23) = 4*23-2 = 90


direct variation means that y = kx
So, plug in the numbers and find k.
