Answer:
b=2/3
Step-by-step explanation:
The table is given as:

The exponential function is given in the form

where a is the initial value and b is the multiplicative rate of change
When x=1, y=9, we have:

When x=3, y=4, we have:

Dividing the two equations:

The multiplicative rate of change, b is 2/3.

Answer: OPTION D.
Step-by-step explanation:
The vertex form of a quadratic function is:

Where (h, k) is the vertex of the parabola and "a" is the coefficient of the squared in the parabola's equation.
We know that the vertex of this parabola is at (5,5) and we also know that when the x-value is 6, the y-value is -1.
Then we can substitute values into
and solve for "a". This is:
