Write the equation as such and narrow down x value being 4
The number is seven because 7×7 = 49 and 49-3 = 46
Answer:
if f(x) = ax + b then f-1(x) = (x - b)/a
Step-by-step explanation:
Now
f(x)=ax + b
then y = ax + b
interchanging x and y , we get
or, x = ay + b
or, x - b = ay
or, (x - b)/a = y
therefore,f-1(x) = (x - b)/a
G(x)=x+7 is the translation
One has 21 and other has 12
