Answer:
1) 1st graph below x-intercepts S={-7,-1}
2) Opens Down <u>Vertex</u>: (-2,4) <u>Axis of Symmetry </u> <u>x-intercept</u>
B <u>Domain:</u>
<u>Range</u>
C This function increases from And decreases from
Step-by-step explanation:
1) The vertex of the parabola is found when we rewrite the common formula:
Into this way:
The Vertex is found by:
That's why we could rewrite the trinomial as this:
Give the equation of the parabola's axis of symmetry, this is given by tracing a vertical line through the parabola vertex.
The intercepts are the roots/zeros:
<u>Domain:</u>
Since the function has no restrictions therefore it is continuous and defined for any value of x ∈ Real Set
<u>Range</u>
As the minimum point -9 is lowest y-coordinate the Range includes this value up to infinite values
(First Graph)
2)
As the parameter a <0 then the graph opens down.
<u>Vertex:</u>
<u>Axis of Symmetry</u>
<u>x-intercept</u>
<u>y-intercept</u>
c=0 then (0,0).
B <u>Domain:</u>
Similarly, since the function has no restrictions therefore it is continuous it is defined for any value of x ∈ Real Set
<u>Range</u>
C
This function increases from Or we can represent this interval like this:
And decreases from
