Question

Plz help me i need it

Answer 1

I'm sorry I'm not entirely sure. But I think -2 and 4. If it's not multiple choice I say -2.

Answer 2

Answer: 4

Explanation:

Average rate of change is the slope between that interval

`f(x) = x^2-3\\\\f(1)=1^2-3\\.\qquad =-2\\,\qquad (1, -2)\\\\f(3)=3^2-3\\.\qquad =6\\.\qquad =(3,6)\\\\slope=(y_2-y_1)/(x_2-x_1)\\\\\\slope=(6-(-2))/(3-1)=(8)/(2)=\large \boxed{4}`
