so in graphing form F(x)=y so y=x^2-8x+16 so x intercept is when the line passes through the x axis or when y=0 y intercept is when the line passes throught the y axis or when x=0
x intercept 0=x^2-8x+16 factor what 2 number multiply to 16 and add to get -8 the numbers are -4 an d -4 0=(x-4)(x-4) set them to zero x-4=0 add 4 x=4
x intercept=4 or (4,0)
y intercept y=x^2-8x+16 x=0 y=0^2-8(0)+16 y=0+16 y=16 y intercept=16 or (0,16)
