Answer:The roots of any quadratic equation is given by: x = [-b +/- sqrt(-b^2 - 4ac)]/2a. Write down the quadratic in the form of ax^2 + bx + c = 0. If the equation is in the form y = ax^2 + bx +c, simply replace the y with 0. This is done because the roots of the equation are the values where the y axis is equal to 0.
Step-by-step explanation:
Answer:
domain) all real numbers
range) all real numbers
Step-by-step explanation:
y=15-9x
there are no illegal values for x that would make the equation invalid so domain is all real numbers
this line is not flat so range is also all real numbers
