CPM Homework Help : AC Problem 3-48

Use your pattern skills to copy and complete the table below.

IN (x)	$2$	$10$	$6$	$7$	$−3$		$−10$	$100$	$x$
OUT (y)	$2$	$6$	$4$			$15$

Hint:

Use the equation $y=mx+b$ to complete the pattern. ( $m=$ growth, $b=$ starting point)

Answer:

IN (x)	$2$	$10$	$6$	$7$	$-3$	$28$	$-10$	$100$	$x$
OUT (y)	$2$	$6$	$4$	$4.5$	$-0.5$	$15$	$-4$	$51$

Explain in words what is done to the input value, $x$ , to produce the output value, $y$ .
Hint (a):
Describe the equation you found from the values in the table.
Answer (a):
Divide $x$ by 2 and then add 1.
Write the process you described in part (a) in algebraic symbols.
Hint (b):
See the first hint and your answer to part (a).
