Question

I'll Give A medal to best answer
Evaluate g(x) for any value within the domain. Interpret the meaning of your solution in the context of your problem

Answer 1

{(0.5,64) , (1,128) , (2, 256)}

Answer 2

Use any two of the points to make the equation of a line...

first find the slope, \[\large m = \frac{ y_2-y_1 }{ x_2 - x_1 }\]

Answer 3

256-128= 128
2-1= 1
m=128/1

Answer 4

Now use that m and any one of the points in: \[\large y-y_1 = m(x-x_1)\]

Answer 5

y-128=128/1(x-256) ?

Answer 6

yes but there's no need for 128/1... 128/1 is 128

Answer 7

okay.

Answer 8

so that's my answer?

Answer 9

No, simplify it first

Answer 10

y-128=128/1(x-256) ?

and 256 is not an x-value, it's a y-value...

Answer 11

y=128x+32896 ?

Answer 12

It sounds a bit bizarre, i think i did it wrong

Answer 13

see my last post\[\large y-y_1 = m(x-x_1) \] (x1, y1) not two y values as you used

Answer 14

y=128x

Answer 15

is that my answer?

Answer 16

Yes

Answer 17

thanks
