A function f (x) is graphed on the coordinate plane.
What is the function rule in slope-intercept form?

y= 2x + 1

Step-by-step explanation:

Given the point (0,1) and (1,3)

You can use the slope formula to get the slope.

y2-y1/x2-x1

3-1/1-0 = 2/1 = 2

Slope = 2

Now rewrite into point-slope formula

y-3=2(x-1)

Distribute

y-3= 2x -2

Add 3 to both sides

y= 2x + 1

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
