Which expression gives the determinant of the matrix
BartSMP [9]

If the matrix is of 2 by 2 then we can find the determinant of the matrix.

\begin{bmatrix}a & b\\ c & d\end{bmatrix}

Then (ad - bc ) gives you the determinant of the matrix.

For example,

\begin{bmatrix} 2 & 4\\  1 & -2 \end{bmatrix}

= (2)(-2) - (1)(4)

= - 4 - 4

\begin{bmatrix} 2 & 4\\  1 & -2 \end{bmatrix} = -8

If you could help I would really appreciate it, but if not that’s fine. Thank you.
dolphi86 [110]

Answer:

3

Step-by-step explanation:

j(2) means that x equals 2...

the first inequality in the function says that x is greater than or equal to 2

the second inequality states that x is greater than 2(not equal to) and is less than or equal to 5

the third one states that x is greater than 5

x applies to the first inequality since we know that x can be equal to 2

Now, to the number before the if

there is a 3 before the if in the first inequality

This means that if x is greater than or equal to 2 the y or the function would equal 3

therefore, j(2) would equal 3

I hope this helps!!!
