Order the quadratic functions from widest to narrowest graph. y=4x^2 y=2x^2 y= 0.15x^2

ANSWER



EXPLANATION

The given quadratic functions are;



and



A fractional coefficient indicates a horizontal stretch.

The smaller the coefficient, the wider the stretch for

and



Also

indicates a horizontal compression.

The higher the value the narrower the graph.

Therefore from widest to narrowest, we have,



See graph.
