1. use the table and the graph to answer the questions. function 1 x 2 3 y 3 5 7 function 2 (a) what is the rate of change for each function? show your work. (b) which function has the greater rate of change?

(a) What is the rate of change for each function? Show your work.function 1
 Function 1 can be graphed and is given by the following line
 y = 2x - 1
 the slope of the line in this case is m = 2

 Function 2 
 For this case you get the slope as follows
 m = (y2-y1) / (x2-x1)
 choosing two points and substituting
 m = ((0) - (4)) / ((- 1) - (0)) = 4

 (b) Which function has the greatest rate of change? 
 Function 2 has the greatest rate of change
 m = 4

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
