Identify the vertex f(x) = 3(x - 2) 2square + 11

Step-by-step explanation:

Vertex form of a quadratic equation is:   y = a(x - h)² + k,  where point (h, k) is the vertex

f(x) = 3(x - 2)² + 11

This is in vertex form, so the vertex is (2, 11)

*it's positive 2 because we are subtracting h in the equation, and we are subtracting positive 2 in our problem

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

a) justify

step-by-step explanation:

justifying is just part of everyday life. justify kind of means proof so i think the answer is a) justify.
