Answer:
Step-by-step explanation:
The functions are written in slope-intercept form.
The graph crosses the y-axis at (0,-2), so the y-intercept is -2.
You can eliminate D because its y-intercept is +2, not -2.
(1,1) and (0,-2) are points on the line.
The slope of the line is (-2-1)/(0-1) = 3
You can eliminate B because its slope is ⅓.
Eliminate C because its slope is -3, not 3.
Answer B
Answer:
Step-by-step explanation:
Here's an example:
x^2 + 6x + 9 = 0
First factorise it:
(x + 3)(x + 3) = 0
So the solution is x = -3 (multiplicity 2)
That is there are 2 roots both -3.
