Question

Write the equation obtained in Part A using function notation.

Answer 1

80x - y = -65

Set it to = 0

80x - y + 65 = 0

isolate y

80x + 65 = y

replace y with f(x)

f(x) = 80x + 65

@amistre64 is that right?

Answer 2

that is function notation yes.

Answer 3

:D
cool, thanks.

Answer 4

do you know the difference between saying:

y = 80x + 65

and saying

f(x) = 80x + 65

???

Answer 5

y = f(x).

Answer 6

There's really no difference.

Answer 7

the term 'y' defines a measurement that is located on the y axis. the y axis does not move around the plane.

the term 'f(x)' defines an object, in this case a line in the plane. the function can be measured at a given point (x) by comparing it to the y axis.

Answer 8

its the difference between a tree [f(x)] and measureing how high the tree is (y)

Answer 9

So y doesn't really matter as long as we know the slope and the x coordinate because we already solved for the y intercept?

Answer 10

y measures f(x), and f(x) is an object that has a measurable value at a given x point.

Answer 11

the distinction is pretty much lost during the math process :) but thats it

Answer 12

Yay! Got moar Rocker?

Answer 13

Just this and five more:

Describe the steps to graph the equation obtained above on the coordinate axes. Mention the labels on the axes and the intervals.

Answer 14

Post in a new question, as per usual. :D

Answer 15

Lol aight.
