Answer:
Step-by-step explanation:
first you have to get the inequality to a point where you can actually graph it
to do this you have to get the x to the same side of the less than symbol
you do this like any other equation, subtract x from the left and right sides because whatever you do to one side, you do to the other
this leaves you with -y < -x + 4
you have to multiply the entire thing by -1 because y cannot be negative
this gives you y < x - 4, now you can graph it
because x is isolated you just have to graph y < -4 like so
im not the best at explanations, i apologize

Answer:
Step-by-step explanation:
This kinda looks like the limiting definition of a derivative.
Anyway, what we are doing with the f(2 + h) is evaluating f(x) with 2+h in place for x. That looks like this:
f(2 + h) = 2(2 + h) - 3 which simplifies to
f(2 + h) = 4 + 2h - 3 which simplifies to
2h + 1
From that we are subtracting f(2). What we are doing with that is evaluating f(x) with 2 in place for x. That looks like this:
f(2) = 2(2) - 3 which simplifies to
f(2) = 4 - 3 which simplifies to
f(2) = 1. Now put those together over h to get:
