F(x) = x2. What is g(x)?

Answer:

D

g(x) = 2 x²

Step-by-step explanation:

You are given a co-ordinate on g(x): (2,1). Plug this into the equaitons to see which one holds true.

A

g(x)=(0.5x)²?

2=(0.5(1))²?

2=0.25? NO

B

g(x)=(0.25x)²?

2=(0.25(1))²?

2=0.0625? NO

C

g(x)=0.5x²?

2=0.5(1²)?

2=0.5? NO

D

g(x)=2x²?

2=2(1²)?

2=2? YES

This could also be solved intuitively, since from the graph, you can see that the x values for g(x) are twice the x values for f(x), but the mathematical method above works too, and is useful if you find reading and assuming things from graphs difficult.

Step-by-step explanation:

Pathagory and Theorem

a^2+b^2=c^2

(x-3)^2+(x-4)^2=6^2

expand:

2x^2-14x+25=36

2x^2-14x-11=0

x=(\sqrt{71}+7)/2

perimeter=(x-3)+(x-4)+6=2x-1

insert the value for x into 2x-1

\sqrt{71}+6=perimeter

Hope that helps :)

<DFA = 180 -(66+56) = 58

<EOB = 360- (90+90+58) = 122

<COB = 360 - (90+90+66) = 114

<COE = 360 - (90+90+56) = 124 so arcCE = 124
answer
<DFA =  58
<EOB = 122
<COB = 114
arc CE = 124
