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!
Please help me with this 3-part question (Differential Calculus:Rules for differentiation):
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
they arnt homework, I want the solutions so I can study them for a test
