Question

Catelynn is using a computer program to graph the function T(w) = –39w – 915. She wants to see the intercepts.

Which minimum values should she use to set up the viewing window?
(Points : 1)
X Min: –1000, Y Min: –30
X Min: –900, Y Min: –50
X Min: –50, Y Min: –900
X Min: –30, Y Min: –1000

Answer 1

Answer 2

find the y intercept
0=-39x-915
915=-39x
x=-23.46

So minimum X should be -30 to see the y-intercept.

The x-intercept
T(w)=-39(0)-915
T(w)=-915

So out of the options, the number that is larger that -915, is -1000.

So it is A,
X Min: –1000, Y Min: –30

with X Min: –1000 we will see the y-intercept -915
and
with Y Min: –30 we will see the x-intercept -23.46
