X^1/2 - x
-2x^3 - x^1/2 - x
-2x^3 - 2x
i think this is it
do parentheses first which gives you 42-4+111 then aubtract to get 38+111 which equals 149
Answer: the answer is B (0,7)
I got I right 100%
Answer:
Since the value of f(0) is negative and the value of f(1) is positive, then there is at least one value of x between 0 and 1 for which f(x) =0.
Step-by-step explanation:
The equation f(x) given is:

For x = 0. the value of the expression is:

For x = 1, the value of the expression is:

Since the value of f(0) is negative and the value of f(1) is positive, then there is at least one value of x between 0 and 1 for which f(x) =0.
In other words, there is at least one solution for the equation between x=0 and x=1.
