Which of the following is the graph of the function y = 2.5sec(x – 5)?

!

Solution:

we are given with the function

The plot of the given function can be found by applying the shifting and stretching property to the graph of the parent function.

Here the parent function is

As we know,

So the parent function gets shifted to right by 5 units.

The required plot of the function and parent function is attached.

The correct option has also been attached.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
