F⁻¹(x) stands for the invers of function f(x). The inverse of f(x) is equal to x. We need to solve for x.
solve for x
f(x) = 2x + 2
2x + 2 = f(x)
2x = f(x) - 2
x =

f⁻¹(x) =

Determine the value of f⁻¹(x) when x = 4
f⁻¹(x) =

f⁻¹(4) =

f⁻¹(4) =

f⁻¹(4) = 1
When x = 4, the value of f⁻¹(x) is equal to 1
The smallest is 6
Three consecutive integers
X. Smallest 6
X+1. 7
X+2. Largest 8
X(X+1)= 4(X+2)+10
X^2+X= 4x+8+10
X^2+X-4x-18=0
X^2-3x-18=0
( X+3)(X-6)
X=-3. X=6
Don't use the negative
Check 6(7)= 4(8)+10
42=42
The greatest six-digit number they could make is 998,877 I know this because I used the largest digits and put them in order from largest to smallest.
Hope this helps
Answer:
Jhon
Step-by-step explanation:
At the rate of 4 minutes per problem, it take Juaqine ...
(4 min/prob)×(6 prob) = 24 min
to solve the problems.
That is more time than it takes Jhon, so Jhon is faster.
