Which function is graphed below?

y = one-third (3) Superscript x

y = 3 (one-third) Superscript x

y = (one-half) Superscript x Baseline + 2

y = (2) Superscript x Baseline minus 1

Which function has a range of y < 3?

y = 3 (2) Superscript x

y = 3 (3) Superscript x

y = negative (2) Superscript x Baseline + 3

y = (2) Superscript x Baseline minus 3

On a coordinate plane, a line increases gradually.

On a coordinate plane, a line decreases gradually.

On a coordinate plane, a line is level and then curves upwards rapidly.

Which properties are present in a table that represents an exponential function in the form when ?I. As the x-values increase, the y-values increase.II. The point (1, 0) exists in the table.III. As the x-values increase, the y-values decrease.IV. As the x-values decrease, the y-values decrease, approaching a singular value.
