Q: Find the following limits or state that they do not exist. Assume a, b, c, and k are fixed real…

A: Simplify the numerator. Thus, the limit becomes,

Q: function is undefined at a specific value, does that mean the limit is automatically infinity or…

A: it doesn't mean that limit is always infinity.

Q: x +7 b. lim x→3 (x - 3)2

A:

Q: 5x lim x→-3 Vx + 4 1

A: This is not indeterminate form so simply put the value of x and simplyfy .

Q: Find the form of the following limit and evaluate it. Vx +3 – V5 lim X+2- X - 2

A:

Q: Name three types of discontinuities. Include an example plot of each and explain how the…

A:

Q: In(x) sin (x – y) 2 lim ( π,υ) + (π,π/2) | Y – x lim (x,y)→(1,1) 1 – y + ln x

A:

Q: 5x b) lim x→-4 (x+ 4)3

A: We have to find the limit.
