The graph represents the piecewise function:

Anna [14]

Answer:

in the attachment

Step-by-step explanation:

Given: Piece-wise function graph.

We need to find the function.

In the graph, we can see a two-piece

For -3≤x≤0

Endpoints on graph (-3,-6) and (0,0)

It is the horizontal line. The equation of the horizontal line is y=k.

Equation: y=3

Now, we write as a piecewise function.

First blank = 2x

Second Blank = 3

Can someone pls help w finding the x and y intercepts of this? y=x^2-2x

AysviL [449]

Answer:

y-intercept is 0, x-intercept is 0 and 1

Step-by-step explanation:

For y-intercept, x=0 :

${ \tt{y = {(0)}^{2} - 2(0) }} \\ { \tt{y = 0}}$

For x-intercept, y=0 :

${ \tt{0 = {2x}^{2} - 2x }} \\ { \tt{2x(x - 1) = 0}} \\ { \tt{x = 0 \: \: and \: \: 1}}$

What is the equation of a line passing through (-3, 7) and having a slope of -1 ?

il63 [147K]

Answer:

Using the information given, we can use the point-slope form:

y - y1 = m(x - x1)

y - 7 = -1(x + 3)

y - 7 = -x - 3

+7 +7

y = -x + 4, this is slope-intercept form

x + y = 4, this is standard form
