Answer:
f(-7)=0.
f(2)=-9/5.
f(3) doesn't exist because 3 isn't in the domain of the function.
Step-by-step explanation:
is the given function.
We are asked to find:
.
f(-7) means to replace x in the expression called f with -7:
Evaluate at
So f(-7)=0.
f(2) means to replace x in the expression called f with 2:
Evaluate at
So f(2)=-9/5
f(3) means to replace x in the expression called f with 3:
Evaluate at
Division by 0 is not allowed so 3 is not in the domain of our function.
(A) The formula for nth bounce is .
(B) 4.43 feet is the maximum height of the ball on the 6th bounce.
<h3>What is an algebraic expression?</h3>An algebraic expression is consists of variables, numbers with various mathematical operations,
Given that,
The height from where the ball is dropped = 20 feet.
Also, the ball bounces and returns to 7/9 to its original height.
(A)
The representation of the maximum height of the ball on the nth bounce can be given as
(B)
The maximum height of the ball on the 6th bounce = 20 (7/9)⁶ = 4.43 feet
