Please help asap Here is the question
Which function defines (f + g) (x)?
f(x)= 5/x +12
g(x) = square root(x-3) + 10
options:
A. (f + g)(x) = 5/x + square root(x-3) + 22
B. (f + g)(x) = (square root(x-3) + 5 / x)+22
C. (f + g)(x) =5/x - square root(x-3) +2
D. (f + g)(x) = 5/x + square root (x) +19

What aspects of lines have to be diffrent

If f(x) = x+8 and g(x) = 4x- 3, find (f+g)(x)

Does the function satisfy the hypotheses of the mean value theorem on the given interval? f(x) = 4x^2 + 3x + 4, [−1, 1] no, f is continuous on [−1, 1] but not differentiable on (−1, 1). no, f is not continuous on [−1, 1]. yes, f is continuous on [−1, 1] and differentiable on (−1, 1) since polynomials are continuous and differentiable on . there is not enough information to verify if this function satisfies the mean value theorem. yes, it does not matter if f is continuous or differentiable; every function satisfies the mean value theorem.
