HELP!!
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?
?

Respuesta :

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
