Question

Help please!!!Which of the quadratic functions has the narrowest graph? 1)y=9x^2 2)y=-0.9x^2 3)y=-10x^2 4)y=2/5x^2

Answer 1

Option 3) y = -10x²

Explanation:

If a quadratic function is in the form of

y = ax² + bx + c

Then coefficient 'a' decides how much narrow will be the graph.

Now from the given options, option C (y = -10x²) will be the narrowest graph.

Option 3) y = -10x²
