3. Determine if the following are functions or not. Please explain your reasoning

C.it a function ,many to 1 bcz it satisfies the vertical test which the first 1 and the horizontal test which is second 1.B ITS NOT A FUNCTION CUZ IT DOES NOT SATISFY THE FIRST TEST

Step-by-step explanation:

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
