Vertex (2, -5)

#### Explanation:

This function is being expressed under the vertex form:

f(x) = a(x - b) + c,

where the coordinates of the vertex are:

x = b = 2, and y = f(2) = c = -5

Vertex (2, -5)

#### Explanation:

#"the equation of a parabola in "color(blue)"vertex form"# is.

#color(red)(bar(ul(|color(white)(2/2)color(black)(y=a(x-h)^2+k)color(white)(2/2)|)))#

#"where "(h,k)" are the coordinates of the vertex and a"#

#"is a multiplier"#

#3(x-2)^2-5" is in vertex form"#

#"with vertex "=(2,-5)#
