i am completely lost on what steps to take for this. I have a ti-84 calculator for equations, etc if needed. thanks in advance

f(x)=3x-21

L(t) = -2.3 + 0.24t + 0.0027t^2 Question: Find dL/dt for 18 ≤ t ≤ 38, using the limit definition of the derivation and then using differentiation rules.

i have no clue what to due and have a test tommorow

IE: -2x^2 Do I do: -2(x)^2, -2(x^2) or (-2x)^2 I say this because of a problem I have that says "h(x)=-4x^2 -2x+5"

for all x, let f(x) be defined by f(x)=x^2+2x+3

g(x)=3x-17 and h(x)=x^2+17

I am unsure of how to do this problem or even set it up. I didn't know whether to find the slope of the two points or not and was wondering if one of you all could help me. I would really appreciate...

I'm very stuck on this question and I'm not sure how to graph this function.

If f(x)=ln(9x+b), find f^−1(x) in terms of b.

Show that f is a function one-to-one, if and only if f(x) = 0 for x=0. I cannot solve this demonstration, I know that if both elements are the same and their functions are the same, then is one...
