Practice problem
Determine which of the following functions is equivalent to the function y=x2−7.y=x^2-7.y=x2−7.
y=(x−3)(x+4)y = (x-3)(x+4)y=(x−3)(x+4)
y=(x+4)(x−4)−9y = (x+4)(x-4)-9y=(x+4)(x−4)−9
y=((x−2)(x+2))−3y = ((x-2)(x+2))-3y=((x−2)(x+2))−3
y=x2+7y = x^2+7y=x2+7
Type a concept, like “slope” or “photosynthesis”.
