What are the domain and range of the function

Domain: (-∞,∞)

Range: (-∞,∞)

Step-by-step explanation:

The x variable can take any value, because the function does not have any restriction.

The range of the function is the same because this is a polynomical function.

ou would have 12 of each

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
