+593 What are the coordinates of the hole in the graph of the function f(x)?
Which graph represents the function?
+128408 First one
[ x^2 + 3x - 28 ] / [ x + 7] factor the numerator
[ (x + 7) (x - 4) ] / ( x + 7) =
x - 4
The "hole" will occur where x + 7 = 0 ⇒ x = - 7
So plugging in x = -7 into x - 4, we get -7 - 4 = -11
So....the coordinates are ( -7, - 11)
Second one.....the third graph is the correct one
