# Stuck on a question :( watch

1. Hey guys,

stuck on a question in my higher maths homework,

would anybody be able to help, not give me the answer but tell me what i need to do to arrive at the answer ?

thanks,

Lewis,

5a) The diagram shows a graph of the form y=bX ( "b" to the power of "x").
i) Find the value of b.

photo of the graph ; http://www.facebook.com/profile.php?id=549382566#!/photo.php?pid=5167378&fbid=45364 7607566&id=549382566

its the graph at the bottom of the page . point (3,8).
2. look where the x coordinate is zero....

the bear

3. I can't see the graph, but if its of the form , just plot a graph of logy and xlogb, and the gradient will tell you the value of x. From there it should be easy to work out b
4. thanks for the replies

would you guys say this is the right answer ..

all my working ;

Point (3,8) lies on the curve, so -

y=bx
8=b3
b3=8
b= "cube root of" 8
b=2?

thanks,

Lewis.
