<u>Marta made a mistake at step 1</u>
- 4 log₅ x = log₅ 4x - wrong
- 4 log₅ x = log₅ x⁴ - correct
<u>Property to be used </u>
The vertex form of all expressions is given below.
We have given that the expressions
We have to write the function in vertex form.
<h3>What is the vertex form of the equation?</h3>
The vertex form of a quadratic function is given by f (x) = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.
Therefore the first equation

it can be written as

The second equation can be written as

vertex for is,

The third equation is,

Vertex form is,

Forth equation is,

Vertex form is,
