If f of x is equal to x squared plus 1 and g of x is equal to x minus 4 , which value is equivalent to open paren f circ g close paren times 10 ?

The notation (f ∘ g)(10) means first evaluate g at 10, then use that result as the input to f. Since g(10) = 10 − 4 = 6, we get f(6) = 6² + 1 = 37. The correct choice is 37.
