1. what are the x-intercepts of the quadratic function? f(x)=x^2+2x−24 ? and ? 2. let f(x)=x^2+17x+72 what are the zeros of the function? ? and ? 3. let f(x)=x^2+6x+11 . what is the minimum value of the function? ?
f(x)=x^2+2x−24 x intercept is where y=0 let f(x)=y x^2+2x−24=0 (x+6)(x-4) ,x=-6, x=4
2)
f(x)=x^2+17x+72 x^2+17x+72 =0
(x+8)(x+9) x= - 8,- 9
3) f(x)=x^2+6x+11 x=-3 minimum
