Answer: 10
Step-by-step explanation:
plug in 3 where x is.
3^2 = 9
9+1 = 10
The answer is 10
f(x)=x^2+1
If f(3) then you would plug that in with each x which gets you
f(3)=3^2+1
Then you figure out what 3^2 equals
(It’s should be nine) This gets you
f(3)=9+1
Which gets you
f(3)= 10
f(x)=x^2+1
If f(3) then you would plug that in with each x which gets you
f(3)=3^2+1
Then you figure out what 3^2 equals
(It’s should be nine) This gets you
f(3)=9+1
Which gets you
f(3)= 10
