Answer:
f(2) = -6
f inverse of 1/2 is 17/2
Step-by-step explanation:
We are given a function
To solve for part (a), we have to substitute x = 2 in f(x).
Therefore, f(2) is -6.
Now we solve for part (b), we see the notation which is a minor different similar to f(x). We see that there is exponent of -1 between f and 1/2. The part (b) indicates that the function is an inverse of f(x).
To solve for part (b), first we solve for x in the function. Let f(x) = y.
Multiply both sides by 2x-5.
Divide both sides by y-term.
Then swap x and y which we receive
Therefore,
Thus,

Answer:
2x2 - x + 2 Changes made to your input should not affect the solution:
(1): "x2" was replaced by "x^2". 1 more similar replacement(s).
Step-by-step explanation:
2x3 - 5x2 + 4x - 4
Simplify ——————————————————
x - 2
Checking for a perfect cube :
3.1 2x3 - 5x2 + 4x - 4 is not a perfect cube
Trying to factor by pulling out :
3.2 Factoring: 2x3 - 5x2 + 4x - 4
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: 4x - 4
Group 2: 2x3 - 5x2
Pull out from each group separately :
Group 1: (x - 1) • (4)
Group 2: (2x - 5) • (x2
5036 is the divisor hope that helped
