Which graph shows a linear function

Last (bottom right) is the linear function.

Step-by-step explanation:

Since linear function is always in the form of y = mx + c

where m is the slope of the line and c is the y intercept of the line.

In the picture attached a straight line is given only in last ( bottom right). In this  graph we can calculate the slope and y intercept. All the points being plotted lie on a straight line.

answer: true

step-by-step explanation:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
