Answer: (-2, 2) and (4, 8)
There are two solutions because the two functions cross each other twice.
Answer:
Shift the parent function to the left by one unit
Step-by-step explanation:
The given function is
The parent function is
The transformation applied to the parent function to obtain the given function is of the form,, which is a horizontal shift to the left by one unit.
To graph we shift the graph of to the left by one unit.
Answer: Each ticket costs $32
=========================================================
Explanation:
Let x be the cost of one ticket. If four people buy a ticket each, then they collectively spend a total of 4x dollars for those tickets. Add on 4*3 = 12 dollars from the fact that they bought the ice cream, and we arrive at the expression 4x+12. This is the total amount spent in dollars for the tickets and ice cream combined.
Set this expression equal to 140 and solve for x
4x+12 = 140
4x = 140-12
4x = 128
x = 128/4
x = 32
This says that each ticket costs $32
If one ticket costs $32, then four of them cost a total of 4*32 = 128 dollars. Add on the $12 spent on the ice cream to get 128+12 = 140, which helps verify we have the correct ticket price.
Another way to verify is to replace x with 32 in the original equation we set up, then simplify like so
4x+12 = 140
4*32+12 = 140
128+12 = 140
140 = 140
This is very similar to the previous verification technique used earlier.
