this is a sketch of the curve with equation y=f(x) the vertex of the curve is at (2,-3)

Answer:
see explanation
Step-by-step explanation:
(a)
Given f(x) then f(x) + c represents a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
f(x) + 5 represents a shift up of 5 units, thus
(2, - 3 ) → (2, - 3 + 5 ) → (2, 2 )
(b)
Given f(x) then - f(x) represents a reflection of f(x) in the x- axis
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus
(2, - 3 ) → (2, 3 )
The vertex of the given curve is the minimum point on the curve.
The vertex is given as:
[tex]\mathbf{(x,y) = (2,-3)}[/tex]
(a) The vertex of f(x) + 5
The rule of the given transformation is:
[tex]\mathbf{(x,y) \to (x,y + 5)}[/tex]
So, we have:
[tex]\mathbf{(x,y) \to (2,-3 + 5)}[/tex]
[tex]\mathbf{(x,y) \to (2,2)}[/tex]
Hence, the vertex of f(x) + 5 is (2,2)
(b) The vertex of -f(x)
The rule of the given transformation is:
[tex]\mathbf{(x,y) \to (x,-y)}[/tex]
So, we have:
[tex]\mathbf{(x,y) \to (2,-(-3))}[/tex]
[tex]\mathbf{(x,y) \to (2,3)}[/tex]
Hence, the vertex of -f(x) is (2,3)
