Answer:
- y-intercept: y=9
- zeros: x= -3, -1, 1, 3
Step-by-step explanation:
The y-intercept is where the graph crosses the y-axis. On this graph, that is just below y=10. A reasonable estimate* of the y-intercept is y=9.
__
The zeros are those places on the graph where y=0. The line y=0 is the x-axis, so the zeros are the x-values of the places where the graph crosses the x-axis. Those points are clearly labeled: x = -3, -1, 1, 3.
_____
* Knowing the zeros, you can write a factored-form equation for the graph:
y = (x +3)(x +1)(x -1)(x -3)
You can substitute x=0 in this equation to see what the y-intercept would be:
3×1×-1×-3 = 9
That is, with no scale factor applied to the function, its y-intercept would be 9. This is the same value we estimated above, so it is reasonable to assume that value is correct.
Answer:
1/2x^2
Step-by-step explanation:
f(x)=x^2 so g(x)=1/2x^2
if g(x)=x(x) then the answer is 1/2x^2

Answer:
The slope is 2/3, and the y-intercept is -5 or (0, -5).
Step-by-step explanation:
You can immediately read off the y-intercept. The line intersects the y-axis at (0, -5).
You can also see that the line goes through (-6, -9).
As we move from (-6, -9) to (0, -5), x increases by 6 and y increases by 4.
Thus, the slope is m = rise / run = 4/6, or m = 2/3.
The slope is 2/3, and the y-intercept is -5 or (0, -5).
