## anonymous one year ago Which equation has a narrower graph than y=4x^2? y =1/3x^2 y = 5x^2 y=1/7x^2 y=2x^2

why?

the graph was narrower. but im not sure, just a bit confused

Basically the large your scaling factor, coefficients in front, the larger your y-values will be. So the y-value when x=5,for instance, plotted on y=4x$$^2$$ compared to y=5x$$^2$$ will be less narrow. Another way to look at it, is if the scaling factor, or coefficient, gets bigger, then your function will approach $$+\infty$$ a LOT laster in the $$+y$$ direction

faster*

the coefficient determines the "growth" factor so the higher the number the higher the y-value for that particular x..
