Order the group of quadratic functions from widest to narrowest graph.
y = -7x^2, y = -1/5x^2, y = -1/3x^2
To determine which quadratic function has the widest graph, we can compare the coefficients of the x^2 term. The greater the coefficient, the wider the graph.
The three quadratic functions are:
1) y = -7x^2
2) y = -1/5x^2
3) y = -1/3x^2
Comparing the coefficients, we see that:
1) -7 > -1/5
2) -1/5 > -1/3
Therefore, the order from widest to narrowest graph is:
1) y = -7x^2
2) y = -1/5x^2
3) y = -1/3x^2
