Given:
The equation of a quadratic function is:
To find:
The equation of the axis of symmetry for the given function.
Solution:
If a quadratic function is , then the equation of the axis of symmetry is:
...(i)
We have,
Here, . So, the equation of axis of symmetry by using (i), is
Therefore, the correct option is C.
The Answer is -4x^2+10x+4
-4x^2 is not effected, as it has no like terms.
3x-(-7x) is equivalent to 3x+7x which equals 10x.
-5-(-9) is equivalent to -5+9 which equals 4.
The answer for 6x + 3y = 15 is should be x= -1/2 y+5/2
Answer:
3x+s
should be the answer hope it helps
