To find where it cross the x-axis, you would have made y=0 to get your two corresponding points that the graph crossed the x-axis. To find where the function crosses the y-axis you do a similar thing and sub x=0 in and find y
the first question i have is: the function of f is defined by . i know how to find where it crosses the x axis, but what method do i use to find the interception of the y axis?
the second question is (note the info in the first question): the graph of y = f(x) is translated by one unit in the positive x-direction and 4 units in the positive y-direction to give the graph of y = g(x). find an expression for g(x) in the form , where a, b and c are integers.
how would i go about tackling these questions? with particular attention to the second one if possible. thankyou,
mark
ps- the answer to the second is
