b. y = 3/2x - 1/2

c. y = 2/3x + 1/3

d. y = 2/3x - 1/3

On a piece of paper graph f(x)=5•(0.4)^x

Tom had a total of $220 and he spent $35 on a basketball ticket . what percent of his money did he have left?

Sample response: if the graph passes the horizontaline test, then the function is one to one. functions that are one to one have inverses that a therefore, the inverse is a hinction compare your response to the sample response above. what did you include in your explanation? a reference to the horizontal-line test d a statement that the function is one-to-one the conclusion that the inverse is a function done
