Ok, I answered question 1. Just in degrees. It is simple the
)
graph moved 45 degrees back.
(b) You know the x-axis intercepts. They are

and

. They are simple the places where the original
)
crosses the x-axis but

those values.
(c)
=0.5)
There are two possible values of
=0.5)
Now you also are told to find
all intercepts, so also y axis. Simple make x=0 and calculate the value of y through the equation to get

They are:

and

. So you simply now equate this back into the equation.
And you will get

and

.
Hope that helps.
