Write the function for the graph.

artcher [175]

Answer:

$f(x) =3 * (4)^x$

Step-by-step explanation:

Given

$(x_1, y_1) = (1,12)$

$(x_2, y_2) = (0,3)$

Required

The function of the graph (exponential function)

An exponential function is represented as:

$f(x) = ab^x$

For $(x_1, y_1) = (1,12)$ , we have:

$12 = a * b^1$

$12 = a * b$

$12 = a b$

For $(x_2, y_2) = (0,3)$

$3 = a * b^0$

$3 = a * 1$

$3 = a$

$a = 3$

Substitute: $a = 3$ in $12 = a b$

$12 = 3 * b$

Divide both sides by 3

$4 = b$

$b =4$

So, we have:

$f(x) = ab^x$

$f(x) =3 * (4)^x$

Is 1/2 greater than 3/4

trasher [3.6K]

So,

In order to determine which fraction is greater, we have to have common denominators.

LCM of 2, 4 = 4

$\frac{1}{2}* \frac{2}{2} = \frac{2}{4}$

Now we can determine.

$\frac{2}{4} < \frac{3}{4}$

A line has a slope of 1/5 and a run = 30. What is the<br> rise?

pashok25 [27]

Answer:

Step-by-step explanation:

$slope=\dfrac{rise}{run}\\\\\text{We have}\\\\slope=\dfrac{1}{5},\ run=30\\\\\text{Substitute:}\\\\\dfrac{1}{5}=\dfrac{rise}{30}\qquad\text{cross multiply}\\\\5rise=(1)(30)\\\\5rise=30\qquad\text{divide both sides by 5}\\\\\dfrac{5rise}{5}=\dfrac{30}{5}\\\\rise=6$
