Video 3.English Solving Problem
1. The figure above shows the graph of y=g(x).
If the function h is defined by h(x)
h(x)=g(2x)+2
h(1)=g(2)+2=1+2=3

2.Let function f be fined by f(x)=x+1.
If 2f(p)=20,what is the value about f(3p)?
f(3x)…?
f(x)=x+1
2f(p)=20
f(p)=10
f(x)=x+1
f(p)=p+1=10
p=9
so,f(3p)=f(27)=27+1=28

3.In the x-y coordinate plane ,the graph of x=y2-4.
Intersects line l at (0,p) and (5,t).
What is the greated possible of the slope of l
