Need Help, Fan and Medal, can't understand this.

Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 2^−x and y = 4^x+3 intersect are the solutions of the equation 2^−x = 4^x + 3. (4 points)

Part B: Make tables to find the solution to 2^−x = 4^x+3. Take the integer values of x only between −3 and 3. (4 points)

Part C: How can you solve the equation 2^−x = 4^x+3 graphically? (2 points)

Is there supposed to be something in that large space in the first part?

loganator · Answer

No

Nothing supposed to be in the space

atildathehun · Answer

ok. sorry for not responding. They have this worded horribly

I'll take a screen shot

There it is

atildathehun · Answer

hm, I want to say because they are the equation. but I am fairly sure that will not get you very far.

atildathehun · Answer

So the best thing I can come up with is,  the x-coordinate of the intersection is the solution to 2−x=4x+3 because that's the point both graphs share.

sorry I could not be more help, that one is worded really strangely.
