The standard form of a quadratic equation is
,
where ,
, and
are coefficients. You want to get the given equation into this form. You can accomplish this by putting all the non-zero values on the left side on the equation.
In this case, the given equation is
Since is on the right side of the equation, we subtract that from both sides. The resulting equation is
Looking at the standard form equation , we can see that
Answer: The axis of symmetry is x=1.
Explanation:
The given function is,
The degree of the equation is 2. SInce it is a quadratic function therefore the graph of the function is a parabola.
The axis of symmetry of a parabolic function is a vertical line,
Since the value of a is 5m b is -10 and c is 7, So the axis of symmetry is,
Therefore, the axis of symmetry is x=1.
