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

Because the tens place is 4 and unless it’s 5 or above the hundreds place doesn’t go up (hopefully that makes sense)
Answer:
h(x) = 5x - 3
Step-by-step explanation:
f(x) = 3x-7
g(x) = 2x+4
3x-7 + 2x+4
5x-3

Answer:
B) −3(x − 1.7)
Step-by-step explanation:
Apply the distributive property of multiplication over addition or over subtraction in each case, which is a(b + c) = ab + ac or a(b - c) = ab - ac.
A) −3(x + 1.7) = = -3(x) + (-3)(1.7) = -3x - 5.1
B) −3(x − 1.7) = -3(x) - (-3)(1.7) = -3x + 5.1 <------------ answer
C) 3(x + 1.7) = 3(x) + 3(1.7) = 3x + 5.1
D) 3(x − 1.7) = 3(x) - 3(1.7) = 3x - 5.1
Answer:
X equal quality negative B times y minus C all over A
Step-by-step explanation:
Subtract By and divide by A:
Ax + By = -C . . . . starting equation
Ax = -By -C . . . . . subtract By from both sides
x = (-By -C)/A . . . . divide both sides by A
