Rewrite the rational expression with the given denominator for 7/20y = ? /40y^3

7            ?

    =  

20 y     40 y^3

to get the denominators to match we need to multiply by 2y^2

what we do to the bottom we do to the top

7*2 y^2

14y^2

7            14y^2

    =  

20 y     40 y^3

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4
