Question

sketch a graph of y=xpower of 2
if the graph is translated 1 unit to the left, write down the equation of the new graph (3)marks

Answer 1

You know there is a vertex at x=0.
If you shift the graph 1 unit to the left, what does x have to be to produce a vertex at -1?

Answer 2

NEW EQN OF GRAPH IS (1-x^2)=y

Answer 3

Nope...

Answer 4

you must first draw a table from negetive 3 to positive 3 and in the place of x you must put those numbers e.g. y=x^2 therefore -3^2 -3 is in (x)'s place.

Answer 5

you still there bra

Answer 6

See y = x^2

Now plot graph for this and you will get

Now what will happen when you move this graph to the left by 1 unit ??
