Question

Which of the following could be the equation of the quadratic shown below?

Answer 1

option A

Explanation:

There's no data provided in the graph. We can interpret from the options provided .

• Firstly we see that the parabola opens downwards , so the coefficient of a will be negative .

• Secondly we can observe the graph cuts y axis above the x axis . So the sign of constant will be positive .

All these matches with option a . Hence option A is correct .

`\implies y = -2x^2 + 8x + 7`
