P=2x-7 + 5x-3 +2x-2
P= 9x -12
The answer is x=1/3
Shall I show the steps?
The answer is that f-1(3) = 7.
In order to find the answer, we first must find the inverse function. The f-1 indicates that we are looking for an inverse. To find any inverse, we first must switch the x and f(x) values. We then solve for the new f(x), which gives us the inverse.
f(x) = (2x - 2)/4 ----> Switch x and f(x)
x = (2f(x) - 2)/4 -----> Multiply both sides by 4
4x = 2f(x) - 2 ----0-> Add 2 to both sides
4x + 2 = 2f(x) ------> Divide both sides by 2
f-1(x) = (4x + 2)/2
Now that we have the inverse function, we can put in 3 and find the answer.
f-1(x) = (4x + 2)/2
f-1(3) = (4(3) + 2)/2
f-1(3) = (12 + 2)/2
f-1(3) = (14)/2
f-1(3) = 7
We must first write this down as the exponential equation provided. This equation is 8^2 = 64. Now, we must use the y = log(b)x logarithmic form to convert the b^y = x exponential equation. by looking at the equation, we know that y = 2, b = 8, and x = 64. Now, we must simply plug these values into the logarithmic equation. This gives us an answer of 2 = log(8)64. The parentheses means subscript.
Hope this helps!
Answer:
The domain of a cube root function is the set of all real numbers. Unlike a square root function which is limited to nonnegative numbers, a cube root can use all real numbers because it is possible for three negatives to equal a negative.
