To find the equation, find the slope from the two points. The slope formula is (y1-y2)/(x1-x2). Plugging in the two points, you should get 3 as your slope. 

As a line, the answer would be y=3x. Therefore, y=3x represents the function described.

The graph of f(x) = 2x + 4 shifts five units to the right when it is replaced with the graph of f(x) = 2x - k. What is the value
DIA [1.3K]
<h2>Answer</h2>

C.) 1

<h2>Explanation </h2>

Remember the rules for shifting functions:

f(x)+b shifts the function b units upward

f(x)-b shifts the function b units downward

f(x+b) shifts the function b units to the left

f(x-b) shifts the function b units to the right

Since we want tho shift f(x)=2^{x+4} 5 units to the right, we are using the rule: f(x-b) shifts the function b units to the right; in other words, we need to subtract 5 units to the input of the function:

f(x)=2^{x+4-5}

f(x)=2^{x-1}

But notice that there is already a negative sign in f(x)=2^{x-k}, so to get f(x)=2^{x-1}, k must be equal to positive 1.

Kobotan [32]

Answer:

1) 69.5

2) 678.6

Step-by-step explanation:

pi3^2=28.27*9=254.5    18*18=324-254.5=69.5

pi24^2=1809.6*.5=904.8 pi6^2=113.1*.5=56.55*4=226.2  904.8-226.2=678.6
