calculus!! urgent: Find intervals of increase, decrease for f(x) = e^(7x) + e^(−x)

f(x) = e^7x + e^−x

(a) Find the intervals on which f is increasing. (Enter your answer using interval notation.)

Find the interval on which f is decreasing. (Enter your answer using interval notation.)

(b) Find the local minimum value of f.

can someone please help me solve these questions please

Using your graphing calculator, plot the function first.

What do you observe?

When you review (or "preview") your post and see that much extraneous (and potentially confusing) information (in this case, needless image sets) were copied over in your copy-n-paste from your online assessment, it might be considerate to edit your post to highlight the useful content. For instance:

For the function f (x ) = e7x + e-x, do the following:

(a) Find the intervals on which f (x ) is increasing and decreasing.
(b) Find the local maximum value of f (x ).

Then you'd show your efforts so far.
