Answer:
The measure of arc AB is 126°.
Step-by-step explanation:
It is given that point C is the center of the circle. The measure of angle ACB is 3x + 120. Arc AB measures 65x – 4.
The measure of central angle is equal to the measure of arc.
Solve this equation for x.
Divide both the sides by 62.
The value of x is 2.
The measure of arc AB is
Therefore the he measure of arc AB is 126°.

Step-by-step explanation:
Quadratic function-
It is a function that can be represented by an equation of the form , where
In a quadratic function, the greatest power of the variable is 2.
As in the first option the highest power is 3, so it is not a quadratic function.
Even though the power of x is 2 in the third option, but as it is in the denominator, so the overall power of x becomes -2. Hence it is not a quadratic function.
As the coefficient of is 0 in case of fourth option, so it is not a quadratic function.
Equation in option 2 satisfies all the conditions of quadratic function, hence it is the quadratic function.
