5. The graph below displays the currency rate between the US Dollar and the Euro at some point in 2010.
Currency Exchange Rate
3
US Dollars
1 2 3 4 5
Euros
Part A
Determine the exchange rate between Euros and US Dollars from the graph.
Part B
Explain how the exchange rate relates to the slope of the line in the graph.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

the answer is c)8

step-by-step explanaction:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
