Question

If the value of a is between 0 and 1 in f(x) = ax?, how does the graph compare to f(x) = x?

above f(x) = x^2
narrower than f(x) = x^2
wider than f(x) = x^2
below f(x) = x^2

Answer 1

As we can see from the graphs, when 0 < |a| < 1 (|a| means absolute value of a), the parabola appears wider. When |a| > 1, the parabola appears thinner. When a is positive, the parabola opens upwards; when a is negative, the parabola opens downward.

Answer 2

it’s gonna be wider i took the test
