Answer 1

What's the new question?

Answer 2

wait

Answer 3

Alrighty

Answer 4

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

Answer 5

I don't remember anything about exponential functions sadly.

But possibly @jim_thompson5910 could assist you

Answer 8

how far did you get HelpPleaseAlgebra?

Answer 9

Not passed reading eat

Answer 10

it**

Answer 11

do you remember how to solve a system of linear equations?

Answer 12

yes kind of

Answer 13

how would you do it visually?

Answer 14

aka using a graph

Answer 15

the intercept is the solution

Answer 16

where they cross is the solution

Answer 17

the same applies to part A

Answer 18

no i tried that it dosent wook

Answer 19

so graph y = 2^(-x) and y = 4^x + 3

Answer 20

where they cross is where the solution is

Answer 21

it dosent work

Answer 22

what do you mean?

Answer 23

it does work

Answer 24

but how would i explain that

Answer 25

it's the same basic explanation for how to visually solve a system of linear equations

you're looking for the point for when x is the same for both equations and for when y is the same for both equations...aka...the point of intersection

Answer 26

okay what about part b

Answer 27

to make a table, you plug in various values of x to get corresponding values of y

Answer 28

so plug in x = 0 to get the y value and you'd record it in the table

Answer 29

and you'd keep going for other x values

Answer 30

ok i got it thanks

Answer 31

but stick around to see if i need clearification
