Help! I have looked at so many lessons on writing exponential functions from a graph and nothing has helped.
Over [174]

Answer:

y = 8(-\frac{1}{2})^x

Step-by-step explanation:

Let the equation of the exponential function is,

y = a(b)ˣ

Since the graph of this function passes through two points (4, \frac{1}{2}) and (3, -1)

For the point (4, \frac{1}{2}),

\frac{1}{2}=a(b)^4 ---------(1)

For second point (3, -1),

-1 = a(b)³ ---------(2)

Divide equation (2) by equation (1),

\frac{\frac{1}{2}}{-1} = \frac{a(b)^4}{a(b)^3}

-\frac{1}{2}=b^{(4-3)}

-\frac{1}{2}=b

From equation (2)

-1 = a(-\frac{1}{2})^3

-1 = -\frac{1}{8}a

a = 8

Therefore, equation of the exponential function will be,

y = 8(-\frac{1}{2})^x

BaLLatris [955]

Answer:

-6x+2y=\frac{3}{2}

Step-by-step explanation:

The equation Thomas wrote is:

y=3x+\frac{3}{4} ...equation 1

Let us subtract 3x from both sides to get:

-3x+y=\frac{3}{4}

We now multiply through by 2 to get:

-6x+2y=\frac{3}{2} ....equation 2

We can see that equation one and two are equivalent and hence have the same solution.

Therefore Sandra's equation is -6x+2y=\frac{3}{2}
