Answer:
y = 7 
Step-by-step explanation:
Use the given ordered pairs to find a and b
Using (0, 7 ), then
7 = a 
( = 1 ), thus
a = 7
y = 7 
Using (5, 1701 )
1701 = 7 
( divide both sides by 7 )
243 = ( take the fifth root of both sides )
b = ![\sqrt[5]{243}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B243%7D)
= 3 , thus
y = 7
Work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100. If your answer is a negative number then this is a percentage decrease.
