F(x)=x2,
g(x)=f(3x)=(3x)2=9x2
Now to graph y=9x2. This is a parabola (U-shape), vertex at (0, 0), symmetric aroung y axis. When x=1/3 or -1/3, then y=1.
So, try to draw the graph.
Answer:
You are correct.
Step-by-step explanation:
What you do is you add them together which is 2x and it stays in the square root. You are correct.
I believe it's A. Hope it helps :)
The answer is B there you go have a nice day
Area = (14 x 20) - ( 5 x 9)
Area = 280 - 45
Area = 235 square cm
