Let y be your total price for buying juice at the farmers market. And x be the amount of juices you buy. If each juice cost 5 bucks then you multiply 5 by x(amount of juice) to get y(your total)
Answer:
Step-by-step explanation:
= x - 5 ( x ≥ 3 )
( )² = ( x - 5 )²
x - 3 = x² - 10x + 25
x² - 11x + 28 = 0
(x - 4)(x - 7) = 0
= 7
= 4
Check the answer:
1). x = 7
= 7 - 2
√4 = 2
2 = 2
2). x = 4
= 4 - 5
1 = - 1 (False statement) ⇒ x = 4 is an extraneous solution.
Answer:
A relation is a function if the x-values map to only one y-value. In other words, if a relation is one-to-one or many-to-one it is a function.
