42%= = 0.42
X/28 = 5/7
x = 28 * 5 / 7
x = 20
answer
x = 20 ft
F(10) = (10)^2 + 1
= 100 + 1
= 101
Answer:
Step-by-step explanation:
The inverse of a function is when the x and y are swapped. So the first step is to write f(x) as y and then swap the x and y
Original Equation:
write f(x) as y (since that's what it represents)
Swap x and y
Square both sides
Add 1 to both sides
So this gives you the equation:
