Write an equation for the graph​ below, which represents an exponential function f with base 2 or​ 3, translated​ and/or reflect
evablogger [386]

Answer:

f(x) = 2*2^x + 3

Step-by-step explanation:

The model for an exponencial function is:

f(x) = a*b^x + c

'c' is the value of the asymptote, so we have c = 3.

To find the value of 'a', let's use the point (0,5):

5 = a*b^0 + 3

5 = a*1 + 3

a = 2

Now, to find the value of 'b', let's use the point (1, 7):

7 = 2 * b^1 + 3

7 = 2b + 3

2b = 4

b = 2

So our function is:

f(x) = 2*2^x + 3

Let's check if the point (-1, 4) is inside our function:

4 = 2 * 2^{-1} + 3

4 = 1 + 3

4 = 4\ (correct)

What does origin mean
Artemon [7]

Answer: (0,0) on a coordinate plane

Step-by-step explanation:

The word origin has many definitions, but I see that you put this topic question under mathematics, So you are talking about an origin on a coordinate plane.

Origin means start or beginning, on a coordinate plane (Consisting of two lines, one vertical, the y-axis and one being horizontal, which is the x-axis), you would find the Origin in the middle of the place that the x-axis and the y-axis intersect

In the area where those axis's intersect is known as the origin and is also known as the points (0,0)

Write in slope intercept form<br><br> 2y+x=1
irga5000 [103]

Answer:

y = -x/2 + 1/2 or

y = -1/2 x + 1/2

(these are equivalent)

Step-by-step explanation:

Slope-intercept form is:

y = mx + b

So we have to get the y all by itself on the left.

2y + x = 1

Subtract x from both sides.

2y = 1 - x

Divide both sides by 2. Divide all the terms by 2.

2y/2 = 1/2 - x/2

Simplify.

y = 1/2 - x/2

Rearrange the terms on the right side so that the x term is first and the constant is last.

y = -x/2 + 1/2

I think this is a good, reasonable and correct answer. But maybe you really want to see that m number (the slope) out in front of the x. Then you can write is as:

y = -1/2 x + 1/2
