Answer:
choice B) yes; only one range value exists for each domain value---------------------------------
---------------------------------
Explanation:
The inputs are x = -3, x = -1, x = 1, x = 5. They are the first coordinate listed of each point. We don't have any x values repeating so this means we have a function. Each input leads to exactly one output which is what
choice B is stating. The domain is the set of allowed inputs, or x values. The range is the set of possible y outputs.
If we had something like (1,2) and (1,5) then the input x = 1 leads to more than one output (y = 2 and y = 5). This example means we don't have a function
If you graph the points (-3, -2), (-1,0), (1,0) and (5,-2) as shown in the attached image, then you'll notice that it is impossible to pass a single line through more than one point. Therefore this graph passes the vertical line test visually proving we have a function.
Going back to the example with (1,2) and (1,5), plotting these two points leads to the vertical line test failing implying we don't have a function.

Answer:4x^2 +28x +49=(2x +7)^2
Step-by-step explanation:
a2±2ab+b2=(a±b)2
In this case
a=2x and b=7 ...
4x2+28x+49=(2x)2+(2⋅
(2x)⋅
7)+72=(2x+7)2
The only one I know is 7. Which is C
