-25/42
Step-by-step explanation:
Answer: f⁻¹(x)=(x-7)²
Step-by-step explanation:
To find the inverse function, we want to switch the y with the x and vice versa. Then we solve for y.
[switch y with x and x with y]
[subtract both sides by 7]
[square both sides]
Now, we know that f⁻¹(x)=(x-7)².
Answer:
a = 4, b = - 
Step-by-step explanation:
Given
= a + b
( multiply both sides by 2 to clear the fraction )
8 - 3 = 2a + 2b
For the 2 sides to be equal , then
2a = 8 ( divide both sides by 2 )
a = 4
and
2b = - 3 ( divide both sides by - 2 )
b = -

g(x) = h(x - 7) + 5
The plus 5 on the outside of the brackets represents the graph moving up by 5 units
The minus 7 on the inside of the brackets represents the graph moving right by 7 units.
Note: When it is on the inside of the brackets, you would do the opposite of what it suggests.
Normally, minus 7 would mean the graph shifts to the left, however, it means the opposite in this case.
