Answer:
D
Step-by-step explanation:
Don't really know how to explain it, but here's an example on how to factor out the coefficient of the variable, hope this explains it!
Factoring out the coeffecient of a variable:
Example:
9x-36
How to factor the coeffecient of the variable: Would then get 9(x-36)
Another example:
1/5k+15
Answer: (1/5)(k+15)
Answer:
My example:
1. Get the equation in the form y = ax4 + bx + c
2. Calculate -b / 4a. This is the x coordinate of the vertex
3. To find the y coordinate of the vertex, simply plug the value -b / 4a into the equation for x and solve for y.
Step-by-step explanation:
y=2x^2 -16x +30
vertex: ( 4, -2)
Focus: (4, -15/8)
Axis of symmetry: x = 4
Directrix: y = -17/8
