When the (align*)x(align*) -value increases by 1, difference of the differences of the (align*)y(align*) -value increases by 4 every time. Since the difference of the differences is constant, the function describing this set of values is quadratic.反馈...
(5-x)(2)-(1)This equation simplifies to0=x-1-5+xso 0=x+x-6We now solve this quadratic equation by factorisation.0=(x+3)(x-2)so x+3=0 or x-2=0thereforex=-3 or x=2These values of.x are now substituted into one of the original equations to find thecorresponding values ...
