The value of f(x) is reflected over the y-axis.

Obtain f(1) as follows,

Draw a vertical line at x=1 to intersect the curve.

From this point of intersection, draw a horizontal line to intersect the y-axis at y=3.

Therefore, the value of f(1) is 3.

Obtain f(2) as follows,

Draw a vertical line at x=2 to intersect the curve.

From this point of intersection, draw a horizontal line to intersect the y-axis at y=8.

Therefore, the value of f(2) is 8.

Obtain f(3) as follows,

Draw a vertical line at x=3 to intersect the curve.

From this point of intersection, draw a horizontal line to intersect the y-axis at y=7.

Therefore, the value of f(3) is 7.
