Which is the equation of the axis of symmetry of the graph of y=-3(x-6)^2+5

axis of symmetry at x=6

Step-by-step explanation:

The given equation is in vertex form

(h,k) is the vertex

Compare the vertex form of the equation with the given equation.

The value of h = 6 and the value of k = 5

So vertex is (6,5)

Axis of symmetry lies at the x coordinate of the vertex

x coordinate of the vertex is 6

So axis of symmetry at x=6

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
