Write a function rule that produces an output of 7 for an input of 1.5.

f(x) = x + 5.5

Step-by-step explanation:

According to the question we need to write a function rule that takes an input of 1.5 and gives an output of 7.

On subtracting 1.5 from 7, we get 5.5.

As 1.5 is an input, we can take an input by variable x and as output is 7, we can take variable y or f(x) for output.

Therefore, we could write a function as :

Output = input + a constant value.

Therefore, the required function rule could be written as :

f(x) = x + 5.5.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
