Answer:

The correct answer is option A.m(7) is undefined.

Step-by-step explanation:

It is given an expression in variable y

m(y) = (2y² + 5)/(y - 7)

To find the value of m(7)

Let m(y) = (2y² + 5)/(y - 7)

m(7) = (2*(7)² + 5)/(7 - 7)    [Substitute 7 instead of y]

 = 103/0

It is undefined

Therefore the  correct answer is option A.m(7) is undefined.

Answer:

m(7) is undefined

Option A is correct.

Step-by-step explanation:

We are given:

[tex]m(y) =\frac{2y^2+5}{y-7}[/tex]

We need to find m(7)

Putting y = 7, and solving:

[tex]m(7) =\frac{2(7)^2+5}{7-7}\\m(7)=\frac{2(14)+5}{0}[/tex]

Anything divide by zero us undefined

so, m(7) is undefined

Option A is correct.
