x = 2, that is B(2) = - 1
From the coordinate diagram, the value of x ( x- axis ) corresponding to the value of y = -1 ( y- axis ) is x = 2
That is the point (2, - 1 )
You need to clarify whether you need the x or the y or both
Answer:
rate of change = -32 feet/second
Step-by-step explanation:
h(t) = 64 – 16t2
t = time (seconds)
Look at the start of time where t = 0
h(t) = 64 - 16 * (0) * 2 = 64 feet
Then look at the specified time where t = 1.25 seconds
h(t) = 64 - 16 * (1.25sec) * 2 = 24 feet
rate of change = rate of change y / rate of change x
x = time, y = height
rate of change = (24 - 64) / (1.25 - 0) = -32 feet/second
