Answer:
1. y=ax^2+bx+c, where a,b, and c are real numbers and a doesn't equal zero
2. Parabola
3. Opens upward
4. Opens downward
5. Vertex
6. Axis of Symmetry
7. Zeros, roots, or x-intercepts
8. You are already given the function so
Step 1: FInd Axis of Symmetry
Equation for Axis of Symmetry: x= - b/2a
Step 2: Find Vertex
- The vertex will be on the Axis of Symmetry, so plug in x then find y.
Equation for Vertex: Ex. The vertex is (-5) which is x now we find y by plugging in -5 whenever we see an X. f(x) = -(-5)^2 - 10(-5)-25=0 our vertex would be (-5,0)
Step 3: Draw your coordinates plane and "dash in" the axis of symmetry. Then plot your vertex
Step 4: Plot your y-intercept and the point symmetrical to it. The y-intercept is "<em>c</em>"
Step 5: Find at least other point on the parabola and draw the curve.
A) Graph A is the answer 100%
Answer:
6
Step-by-step explanation:
root the 216 as it is a cube
:edge *edge *edge =volume
Since all edges are the same, just root it

#8:
Substitute -5 in for x.
y = 9(-5) - 12
y = -45 - 12
y = -57
#9:
Substitute -2 in for x
y = -5(2)² + 18
y = -5(4) + 18
y = -20 + 18
y = -2
The answer is 76.76
Fort you have to find 28% of 292.
28/100 = x/292
100x= 292 x 28
100x = 8176
x= 81.76
Then you have to subtract 5 from 81.76
81.76 - 5 = 76.76
