Question

What is the equation of the parabola ?

Answer 1

• y=ax²+b

b is y intercept,a is coefficient

Here a is 1/12 as every option contains this factor so don't calculate.

As parabola is opening upwards a is positive

and

y intercept is 2

So the equation is

• y=1/12x²+2

Answer 2

• D. y = 1/12x² + 2

Explanation:

As per graph we observe:

• The y-intercept is 2
• The coefficient is positive as the graph opens up

According to the observations, the equation is:

• y = 1/12x² + 2

Correct choice is D
