Evaluate ƒ(x ) = x 2 + 1 for ƒ(-1). A. 0 B. undefined C. 2

2

Step-by-step explanation:

f(-1)=(-1)²+1=1+1=2

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.
