Step-by-step explanation:

The given expression is

\frac{f(b)-f(a)}{b-a}=2

Notice that a and b are elements of the domain and f(a) and f(b) are elements of the range.

Observe the notation used,  an element of the range is always written like f(x) where x is an element of the domain.

Also, notice that this expression is using two pair of coordinates, which are (a, f(a)) and (b,f(b)).

On the other hand, the definition of average rate of change is

r=\frac{y_{2} -y_{1} }{x_{2}-x_{1}  }

Where (x_{1} ,y_{1} )=(a ,f(a)) and (x_{2} ,y_{2} )=(b ,f(b)).

Having said that, the given expression represents an average rate of change in the interval, where the rate is 2. The right answer is the third option.

What are the zeros of the polynomial equation f(x)=x^2-12x+20?
bagirrra123 [75]
f(x)=x^2-12x+20\\\\\text{The zeros:}\\\\f(x)=0\to x^2-12x+20=0\\\\x^2-10x-2x+20=0\\\\x(x-10)-2(x-10)=0\\\\(x-10)(x-2)=0\iff x-10=0\ \vee\ x-2=0\\\\\boxed{x=10\ \vee\ x=2}
