(°□°) I'M STUCK HELP!!!!! FREE MEDAL IF U ANSWER https://www.dropbox.com/s/utlnjfnpy2xkqn8/Screenshot%202015-12-29%2011.35.49.png?dl=0

OpenStudy (boldjon):

0,-8

Nnesha (nnesha):

x-intercepts: point where line intersect the x-axis when y=0|dw:1451407354461:dw| so substitute y for 0 to find x-intercept

Nnesha (nnesha):

do you know how to solve quadratic equation ? there are different methods which one is easy for you ? factoring quadratic formula graphing ??

OpenStudy (boldjon):

i'd say graphing

Nnesha (nnesha):

okay then graph the equation x-intercepts are located on the x-axis

OpenStudy (boldjon):

yeah i did all that and i got 0,-8

OpenStudy (mathmale):

boldjon: Nnesha is asking you to graph\[f(x) = x^2-16x+64.\]

OpenStudy (mathmale):

Where's your graph?? Sorry to have to tell you this, but x=0 is not a zero of f(x).

Nnesha (nnesha):

substitute x and y for (0,8) if you get equal sides at the end then good to go!

OpenStudy (boldjon):

sorry but i don't have scanner to show u-_- and yes THANK YOU IT WORKED

Nnesha (nnesha):

show your work did you substitute x for 0 and y for 8 ?

OpenStudy (boldjon):

i don't have a scanner it's on paper

OpenStudy (boldjon):

but it worked thanks

OpenStudy (mathmale):

Once again, boldjon, 0 is NOT a root of the given function; it's not a zero; it's not a solution. type in your work. or draw your work, using the Draw utility (below)|dw:1451407970029:dw|
