Select the correct functions. Identify the functions that exhibit a removable discontinuity.

x2 + 4x -21

f(x) =

x2 - 13x+42

x2 - 8x +15

i(x) =

X-5

g(x)=

2x2 -5x + 12

2x+3

(x) =

x + 4

-2x +8

X-3

h(x) =

2x2 + x - 15

k(x) =

2x-5

b

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
