**Hint:**

To determine the points of discontinuity for a piecewise function:

Look at the points where the function's definition changes.

Evaluate the function values and limits from both sides at these points.

If the left-hand limit does not match the right-hand limit or the function's value, the function is discontinuous at that point.

**Step-by-Step Solution:**

To determine the points of discontinuity of f, we need to examine its behavior at each possible point of discontinuity.

Case 1: $x < 2$

In this case, $f(x)=2x+3$.

Let's consider the one-sided limits as x approaches 2:

Left-hand limit (LHL): $lim_{x\rightarrow 2^{-}} f(x) = lim_{x\rightarrow 2^{-}} (2x + 3) = 2(2) + 3 = 7$

Right-hand limit (RHL): Since f(x) is not defined at x=2, the right-hand limit does not exist.

Since the LHL does not equal the RHL, f is discontinuous at x=2.

Case 2: $x > 2$

In this case, $f(x)=2x−3$.

Let's consider the one-sided limits as x approaches 2:

Left-hand limit (LHL): Since f(x) is not defined at x=2, the left-hand limit does not exist.

Right-hand limit (RHL): $lim_{x\rightarrow 2^{+}} + f(x)=lim_{x\rightarrow 2^{+}} + (2x − 3) = 2(2) − 3 = 1$

Since the LHL does not exist, we cannot determine whether f is continuous at x=2.

Therefore, the only point of discontinuity of f is $x = 2$.

**Additional Information:**

The graphical representation of f would show a sharp jump at x=2, indicating the discontinuity.

**Note:**

The point x=2 is a discontinuity of the first kind, also known as a jump discontinuity, since the function has different one-sided limits at that point.
