Step-by-step explanation:
Root:(1/2, 0)
Domain: x∈R
Range: y∈R
Vertical intercept: (0, 1)
His total money is: $80
He spent $16 for the entrance of the fair and food.
80-(4+12) = 64
subtracting $1.25 per ride = -1.25x
Therefore gives the function:
f(x) = -1.25x + 64
Just replace the x in the question with -2, and the y with 2.
Therefore, you're doing ((-2)(2²))/7 which is -2 times 2 squared all over 7.
-2 × 2² = -8
-8/7 is your answer.
