Question

The table below shows some values of f(x) and g(x) for different values of x.

x f(x) = 2x + 24 g(x) = 5(0.5)x
-2 20 ?
-1 ? ?
0 ? 5
1 ? 2.5
2 28 ?

Complete the chart and determine the solution of the equation f(x) = g(x)?
x = -2

x = -1

x = 1

x = 20

Answer 2

Can u take a snap shot of the problem because its a but hard to figure out like this.

Answer 3

ok this should work

Answer 4

For this we need to plug in the numbers for x:
f(x) = 2x + 24
f(-1) = 2 x -1 + 24.

Answer 5

Question really quick what does it mean when it says complete the chart to "solve" the equation???

Answer 8

You can either plot them in a graphing calculator or plug in each x value and see which gives you a true statement.

Answer 9

I just don't understand what im supposed to solve for :(

Answer 10

Wait, is that being raised to a power? g(x) = 5(0.5)^x?

Answer 11

yes the power of x

Answer 12

f(x) = 2x + 24

use x = 2 and plug in 2 for every x,

f(2) = 2(2) + 24

f(2) = 4 + 24 = 28

f(2) = 28




g(x) = 5(0.5)^x

g(2) = 5(0.5)^2

g(2) = 5(0.25)

g(2) = 1.25

Answer 13

Try the others on your own. and see which gives you a true statement,

like 7 = 7 <-- true

Answer 14

ok i know how to do that but i just dont know what i am trying to solve for?

Answer 15

You're trying to solve for each of those x values. Which ever gives you a true statement is the correct one.

Answer 16

so would it be x = -1

Answer 17

no try again, it has to be equal like 20 = 20 or 16 = 16

They both have to have the same answer

Answer 18

wait i think im doing it wrong could you explain it real quick?

Answer 19

explain what

Answer 20

f(-2) = 2(-2) + 24

f(-2) = 20

g(-2) = 5*4

g(-2) = 20

Its x = -2 because THEY BOTH EQUAL 20

Answer 21

oh so to find that they were true they had to both equal the same wow im dumb... THank you so much for explaining!
