Find the y-coordinate of the vertex:
f(2) = 2^2- 4(2) - 5.

Step-by-step explanation:

f(2)=2²-4(2)-5

f(x)=x²-4x-5

=x²-4x+4-4-5

=(x-2)²-9

vertex is (2,-9)

y co-ordinate of the vertex is -9

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
