if f(x)= (x-4)(x=3) determine the x intercept of the funtion if
y= -2f(x)...
i just dont know if the -2 affects the answer because that only affects the y co ordinates. in the book it says 4,-3 but i dont know why.
if this is true if the they were asking me to find the y interpct of the function what do i do. THANKS!!!!
