<h3>Uber</h3>
- $5 pickup fee
- $0.25 per mile
<u>Equation</u>
<u>Cost of 5 miles:</u>
<h3>KC yellow Cab Co.</h3>
- $1.75 pickup fee
- $0.75 per mile
<u>Equation</u>
<u>Cost of 5 miles:</u>
- y = 0.75(5) + 1.75 = $5.5
Comparing the cost we see KC yellow Cab Co. is better value for a 5 mile ride.
Step-by-step explanation:
y = ax^n + bx^(n-1) ... + z
(0, 1) tells us that the constant term z = 1.
because x = 0 eliminates all other terms. and as the sum is 1, that means z = 1.
for the other pairs I strongly suspect
(-1, 3) : 2×(-1)² + 1 = 2×1 + 1 = 3
(-2, 9) : 2×(-2)² + 1 = 2×4 + 1 = 9
so, the fitting equation is
y = 2x² + 1
