Thins i explained were
Finding inverse of relations
Writing a Formula for the input of a function
Finding the inverse of a function
Evaluatting a piecewise function
Ex 1;
x < 0 |x-2| x >0| <x+1|
solution;
f(0)=x-2
f(0)=101-2
f(0)=x > 0
f(0)=141 > 0
f(0)=-2
f(0)=4
Graphing a piece wise function
Solution: The domain is all real numbers. The range is y > -4
My Notes:
y=mx+b=
M=Slope
B=Y intercept
m=-1
b=-4
1)y intercept =-4
2) use slope to find 2nd point
3)drew a line threw the points
4) erase the line to the right of x=0
5)>/< = open circle, = closed circle
Writing a piecewise function
Solution:
f(x) ={x< 0:1x +3x > 0.2x - 1 }
answer; m(x) ={x< 0:1x + 3> 0.2x - 1}
My Notes:
1)identify y-intercept (b)
2)pick two points on the line to find the slope (m)
3)substitute m and b into y=mx+b
4)identify the end point and the x-value
5) < = left, > = right
Extra Notes:
g(x)=|x|+3 Up and down
m(x)=|x-2| To the right
m (x)= |x+2| To the left
n (x)= |x+4| Left and Right
