Suppose noodle soup is on sale for $0.75 a can, and you have a coupon for $0.50 off your total purchase. Write a function rule for the cost of n cans of soup. (1 point) Responses C(n) = 0.75and – 0.5 C ( n ) = 0.75 n – 0.5 C(n) = 0.5n – 0.75 C ( n ) = 0.5 n – 0.75 C(n) = (0.75 + n) – 0.5 C ( n ) = (0.75 + n) – 0.5 C(n) = (0.5 + n) – 0.75

C(n) = (0.75n) - 0.5
What is the graph of the function rule? y = |2x| + 1
The graph of the function rule y = |2x| + 1 is a V-shaped graph that opens upwards. It passes through the point (0, 1) and as x moves further away from 0, the value of y increases. The vertical axis intercepts at (0, 1).
