What is the vertex of the function f(x) = x2 + 12x?

(–6, –36)

(–6, 0)

(6, 0)

(6, –36)

Option A is correct

(–6, –36)

Step-by-step explanation:

A quadratic equation is in the form of  ,....[1] then the axis of symmetry is given by:

Vertex of the function is given by:

As per the statement:

Given the function:

          ....[2]

Compare this with equation [1] we have;

a = 1 and b = 12

then;

⇒

⇒x = -6

Substitute the value of x in [2] we have;

⇒f(-6) = -36

⇒Vertex = (-6, -36)

Therefore, the vertex of the function f(x) is, (–6, –36)

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
