How do I draw this on a graph and state the domain + range?

- ( 2 x<-2

- f(x) = < √4-x² -2≤x≤2

- ( -|x| x>2

NOTE: √4-x² all of that is square rooted (i.e. <start square rooting> 4-x² </stop rooting>

Thanks in advance

I missed a lesson that was about **Differential Calculus > Limits**

Can someone please explain because I have no idea about it. I know the easier way by the derivative rule but I need to know how to do this way.

Some of the questions are:

Evaluate

lim (3x)

x->3

lim (x² -2x+1)

x->-2

lim (1 + h)з - 1

- -------------

h->0 h

Thanks in advance, I miy have some more questions later.

Thanks soo much. Fast response too!

Q1) Find the coordinates of the points on the curve y=x²-5x+6 at which the tangent:

A) makes an angle of 45 degrees with the X-axis.

B) is parallel to the line with the equation 3x+y-4=0

C) is perpendicular to the line with the equation 2y-x+3=0

Thanks in advance
