At how many points does the graph of the function below intersect the x-axis?

y = 4 x 2 - 9x + 9

a.0

b.2

c.1

A.0

Step-by-step explanation:

y=4x²- 9x + 9

The function will intersect the x-axis when  y = 0.

4x² - 9x + 9 = 0

a=4, b= -9, c=9

D=b² - 4ac = (-9)²- 4*4*9=81 - 144= - 63

D= -63, D<0, so the equation

4x² - 9x + 9 = 0 does not have real roots. That means that function    y=4x²- 9x + 9 does not intersect x- axis. So, answer is A. 0.

$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
