After placing an equation into his calculator rob got the following table. he then determine that x=6 when f (x) = -4 is he correct? explain

x | f(x)

-4 | 6

-2 | 3

0 | -1

2 | -4

f(6) = - 4 is incorrect.

Step-by-step explanation:

In the given table the values of x and corresponding values of f(x) are given.

The ordered pairs are (-4,6), (-2,3), (0,-1) and (2,-4).

Now, we have to determine the function y = f(x) from any two of the given ordered pair.

The equation of the function is

⇒ -2(y - 6) = 3(x + 4)

⇒ 2y + 3x = 0 ........... (1)

Now, putting x = 6 in the above equation (1), we get y = - 9

Therefore, f(6) = - 9

Hence, f(6) = - 4 is incorrect. (Answer)

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.
