f(4) = 12</h3><h3>
f(5) = 13</h3>
=======================================================
Explanation:
This is a piecewise function as it is composed of two pieces.
The equation for f(x) depends on what x is. Specifically whether it is even or odd.
If x is even, then f(x) = x^2-4. If x is odd, then f(x) = 3x-2
------------
f(4) means f(x) when x = 4. We have an even number input for x, so we'll go with f(x) = x^2-4
f(x) = x^2 - 4
f(4) = 4^2 - 4
f(4) = 16 - 4
f(4) = 12
------------
When x = 5, x is now odd, so use f(x) = 3x-2
f(x) = 3x-2
f(5) = 3(5) - 2
f(5) = 15 - 2
f(5) = 13

Complete Question
When the Olympic Games were held outside Mexico City in 1968, there was much discussion about the effect the high altitude (7340 feet) would have on the athletes. Assuming air pressure decays exponentially by 0.5% every 100 feet, by what percentage is air pressure reduced by moving from sea level to Mexico City?
Round your answer to one decimal place.
....... %
Answer:
The value is 
Step-by-step explanation:
From the question we are told that
The height of Mexico city is h = 7340 feet
The rate at which air pressure decays is 0.5% per 100 feet
From the data given

Answer:
44/7
Step-by-step explanation:
First, carry out the indicated multiplication, using the Distributive Property of Multiplication:
-4x + 2(3x – 1) - 12 = 3x + 30 becomes:
-4x + 6x – 2 - 12 = 3x + 30
Next, combine all the x terms and all the constants. We get:
10x - 14 = 3x + 30, or 7x = 44
Dividing both sides by 7 yields x = 44/7.
