Given the following linear function sketch the graph of the function and find the domain and range. ƒ(x) = -3x + 7

Graph : Attachment

Step-by-step explanation:

Given:

We need to graph it and find the domain and range of the function.

Domain: It is input value of x where function is well defined.

Range: It is output value of f(x)

Now we draw the graph of f(x) using table method.

So, first we have to make the table of x and y

Put x=-1 into f(x)

f(-1)=-3(-1)+7 = 3+7 = 10

(-1,10)

Put x=1 into f(x)

f(1)=-3(1)+7 = -3+7 = 4

(1,4)

Put x=0 into f(x)

f(0)=-3(0)+7 = 0+7 =7

(0,7)

 x     :    -1          0          1

f(x)   :    10        7           4

Now we plot the points on graph. Please find the attachment for graph.

step-by-step explanation:

32.50-7.50=25

225/25=11

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

          72     -     432 - 3 = -363
