Answer:

D.\ (3,\frac{1}{8})

Step-by-step explanation:

Given

y = (\frac{1}{2})^x

Required

Points that lies on the above graph

From the given options, only option D lies on the point and the proof is as follows:

D.\ (3,\frac{1}{8})

This means that:

x = 3;\ y = \frac{1}{8}

Substitute x = 3;\ y = \frac{1}{8} in y = (\frac{1}{2})^x

\frac{1}{8} = (\frac{1}{2})^3

\frac{1}{8} = \frac{1^3}{2^3}

\frac{1}{8} = \frac{1}{8}

See that the values at the right and left hand side of the equation are the same.

This means that, D.\ (3,\frac{1}{8}) lies on y = (\frac{1}{2})^x

deff fn [24]

Answer: The y-value of the vertex is

Step-by-step explanation: we know that

The equation of a vertical parabola into vertex form is equal to

where

(h,k) is the vertex of the parabola

In this problem we have

-----> this a vertical parabola open upward

Convert to vertex form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Factor the leading coefficient

Complete the square. Remember to balance the equation by adding the same constants to each side

Rewrite as perfect squares

The vertex is the point

The y-value of the vertex is
