Answer:

The answer is B

Step-by-step explanation:

Answers talk about rate of change meaning slope.

For function 1 we choose two points, they specify [1,2].

Use the slope formula for points (1,-3) & (2,3) = 6

For function 2, the equation is shown in y-intercept, basically the slope is (1/4)^x and if you replace x with [1,2] you get really low values.

For function 3 is easy since you can count the units with rise/run giving and slope of 2 or 2/1. <em>(2 and 2/1 is the same thing)</em>

Given the function f(x) = 6|x – 2| + 3, for what values of x is f(x) = 39? x = –8, x = 4 x = 8, x = –4 x = 9, x = –4 x = 8, x =

jenyasd209 [6]

x= -4 and x=8
f(x) =6║x-2║+3
39= 6║x-2║+3
36=6║x-2║
6=║x-2║
-(x-2)=6
-x+2=6
x=-4
x-2=6
x=8

Find the focus of the parabola whose equation is y=1/8 x^2

Mama L [17]

Answer:

The focus is: $(0,2)$

Step-by-step explanation:

Given

$y = \frac{1}{8}x^2$

Required

Determine the focus

The focus of a parabola

$(x- h)^2 = 4p(y - k)$

is:

$(h,k+p)$

So, we have:

$y = \frac{1}{8}x^2$

Cross multiply

$8y = x^2$

Rewrite as:

$x^2 = 8y$

Rewrite as:

$(x - 0)^2 = 8(y - 0)$

Express 8 as 4 * 2

$(x - 0)^2 = 4 * 2(y - 0)$

By comparison with: $(x- h)^2 = 4p(y - k)$

$h = 0$ $p =2$ $k = 0$

So, the focus $(h,k+p)$ is:

$(h,k+p) = (0,0+2)$

$(h,k+p) = (0,2)$
