No not always, because x could be a smaller number than y which would make it an negative. If x is bigger than y most likely it will be, but not always.
P(-3)= -2(-3) -2
p(-3)= 6-2
p(-3)= 4
Answer:
y = lnx/ln12
Step-by-step explanation:
Given the function y = 12^x, to find the inverse of the function, we news to write x as a function of y as shown:
Given y = 12^x
Taking ln of both sides
ln y = ln 12^x
ln y = xln12
Divide both sides by ln12
lny/ln12 = xln12/ln12
x = lny/ln12
x = ln(y-12)
Replacing y with x and x with y
The inverse of the function will be:
y = lnx/ln12
5 and 7
5 + 7 = 12
5 x 7 = 35
