Find the inverse of the function f(x)=8^x
1 answer:
Answer:
y = logx/log8
Step-by-step explanation:
To find the inverse of an equation, you switch the locations of x and y, then solve for y.
So in this case, f(x) = y, and your equation is:
y = 8^x
It would become
x = 8^y
There are multiple ways to solve this- one I usually use is logs, so you take the log of both sides.
log x = ylog8
(when you take the log of something the exponent becomes a coefficient)
Then, y = logx/log8
I hoped this helped!

Answer:
when h(x) = 0, x = 7/3
Step-by-step explanation:
0 = 3x - 7
7 = 3x
7/3 = x
Draw a number line with 10 positives and 10 negatives. Count from 0 to 8. Now, from 8, count back 12 spots. From that spot, go back to 0, which is their original position. The number you counted there is your answer.
Answer:
Step-by-step explanation:
-10 ( y-4) + 3y = 5 <--- substitute the value of x into first equation
-10y + 40 + 3y = 5
-7y + 40 = 5
-7y = -35
y= 5
x = 5 - 4
x = 1
The answer is 5.9% I think because you have to round up if it’s 5 and above
