the x-intercept is when y = 0. W(x) = y

OpenStudy (iwanttogotostanford):

so far this is all I've got: -To find the x intercept of W(x) , set W(x) to 0 and then solve for x. The given function W(x) should be zero at whatever point it intersects with x-axis.

@triciaal

OpenStudy (triciaal):

yes you said the same thing twice.

OpenStudy (iwanttogotostanford):

ok is that sufficient do you think for the first part of the question to be answered correctly?

OpenStudy (iwanttogotostanford):

@triciaal

OpenStudy (triciaal):

you don't need to tag me if I am right here reading.

OpenStudy (iwanttogotostanford):

ok sorry

OpenStudy (triciaal):

it sounds better with the 2nd sentence first.

OpenStudy (iwanttogotostanford):

ok thanks! I am stuck on how to find the second part of the question though

OpenStudy (triciaal):

insert "this is the x-intercept."

OpenStudy (triciaal):

for example with a function like (put your example) to construct a rough draft we would choose values of x and find the corresponding value of y . we could also determine the end value behavior of the function.

OpenStudy (triciaal):

***choose both positive and negative values

OpenStudy (iwanttogotostanford):

ok so like: x=1 and then y=-2 ? How many values do i need to choose

OpenStudy (triciaal):

think you should first make up your function. domain set of x-values example { -3 - 2- 1 0 1 2 3 ) range output values lowest to highest end behavior f(-x) and f(x)

OpenStudy (triciaal):

after you have the graph then you can identify where it crosses the x-axis hence see where the intercepts are.
