Answer:
(pi) is irrational ...........
The inverse of the function are respectively; f⁻¹(3) = 2 and f⁻¹(8) = 8.5
<h3>How to find the inverse of a Function?</h3>
The formula to find the equation of this function using two coordinates is;
(y - y1)/(x - x1) = (y2 - y1)/(x2 - x1)
Using the first 2 coordinates, we have;
(y - 1)/(x + 1) = (3 - 1)/(2 + 1)
(y - 1)/(x + 1) = 2/3
3y - 3 = 2x + 2
3y = 2x + 5
y = ¹/₃(2x + 5)
Thus, the inverse is;
f⁻¹(x) = (3x - 5)/2
Thus;
f⁻¹(3) = (3*3 - 5)/2
f⁻¹(3) = 2
Similarly;
f⁻¹(x) = (3x - 5)/2
Thus;
f⁻¹(8) = (3*8 - 5)/2
f⁻¹(8) = 8.5

Answer:
Raul's age is 15 years.
Step-by-step explanation:
r represents Raul's age.
The number of years from the start of the Great Depression to the first presidential election of Richard Nixon is six years less than three times Raul's age.
The first presidential election happened 39 years after the Great Depression and six years less than three times Raul's age is 3r - 6.
Therefore, 3r - 6 = 39
Add 6 to both sides.
3r = 45
Divide both sides by 3.
r = 15
Hence, Raul's age is 15 years.
