Question

how does this g(x)*r(x)=2*0.5(1.1)^x turn into this g(x)*r(x)=x*(1.1)^x, like where did the 2x and 0.5 go?

Answer 1

I assume your original equation is:

g(x)*r(x)=2x*0.5(1.1)^x

Did you miss the x after the 2?

Answer 2

oh yea! sorry its g(x)*r(x)=2x*0.5(1.1)^x

Answer 3

OK - now look at just this product:

2x * 0.5

Can you simplify it?

Answer 4

i dont think so..

Answer 5

what about:

2 * 0.5

Answer 6

yea just multiply them together

Answer 7

and you get?

Answer 8

1... ohhhh 1x = x

Answer 9
