Determine if each graph below represents a function. then state its domain and range. will mark brainliest. need asap its due tomorrow, im

Graph 10 and 12 are both functions while graph 13 is not a function

Step-by-step explanation: The best way to know if the graph is a function is by the vertical line test, if the points on the graph pass through the straight vertical line more than once, it is not a function, but if it passes though the line only once then it is a function. Now for the Domain and range, the best way to see it is as DomainX and RangeY, this is something I learned when I did functions, and it helped me a lot. Now if you look at 10 and 12, both go on infinitely, as they have no stopping point, meaning that the domain would be (-infinity, infinity), and for 13 you can simply put the coordinates for each point in a chart, with your X and Y, remember DomainX and RangeY, this should help you understand which is X and which is Y. I hope this helped a bit. Now for RangeY, for 10, look for the lowest number in the Y axis that the line goes, for this case its, -1, and then look for the highest number on the Y axis that the line goes, aka 3, now use this as a example and you can easily find 12's Range.

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
