What is an equation that is a parabola with a vertex at(-1,-1)

The equation for a parabola is y = ((x - a)^2) + b. There is a shift one to the left (we’ll call that a) and one shift down (we’ll call that b) for the point (-1,-1). Shifts to the left and right are replaced with a and shifts up and down are replaced with b. y = ( x - (-1))^2 - 1. Simplify: y = (( x + 1)^2) - 1

72feet/min

Step-by-step explanation:

The following were obtained from the question:

Distance = 54 yards

But: 1yard = 3feets

Therefore, 54 yards = 54 x 3 = 162feets

Time = 135secs

Recall: 60secs = 1mins

Therefore, 135secs = 135/60 = 2.25mins

The rate of the Zebra = Distance /time

The rate of the Zebra = 162/2.25 = 72feet/min
