Answer:
The graph is a parabola with vertex (0 , -2)
Equation: y = x² -2
For x = -2, y = (-2)² -2 ⇒ y = 4 - 2 ⇒ y = 2
For x = -1, y = (-1)² -2 ⇒ y = 1 - 2 ⇒ y = -1
For x = 0, y = (0)² -2 ⇒ y = 0 - 2 ⇒ y = -2
For x = 1, y = (1)² -2 ⇒ y = 1 - 2 ⇒ y = -1
For x = 2, y = (2)² -2 ⇒ y = 4 - 2 ⇒ y = 2

Answer:
Step-by-step explanation:
step a system of two equations c = child ticket a = adult ticket
eq 1) 2c + 1a = 8.2 multiply by 2
eq 2) 3c + 2a = 14.1
I will multiply eq 1 times TWO and subtract eq 2 from eq 1a)
eq 1a) 4c + 2a = 16.4
eq 2) 3c + 2a = 14.1
subtract (4c - 3c) + (2a -2a) = 16.4 - 14.1
c + 0 = 2.3 euros for one child ticket
Now find the adult ticket price, plug 2.3 for c into eq 1)
eq 1) 2c + 1a = 8.2
eq 1) 2(2.3) + 1a = 8.2 solve for a
4.6 + a = 8.2 substract 4.6 from both sides
a = 8.2 - 4.6
= 3.6 euros for one adult ticket
double check using eq 2) we know c and a values
eq 2) 3c + 2a = 14.1
eq 2) 3(2.3) + 2(3.6) = 14.1
6.9 + 7.2 = 14.1
14.1 = 14.1
I'm 98% sure it would be -24.
Hope this helped you! :)
