Question

Which equation would f(x)=x^2 / 4
appear as when translated up 9 units on a graph?(1 point)
Responses

A) f(x)=9x^2 / 4
f left parenthesis x right parenthesis equals Start Fraction 9 x squared over 4 End Fraction

B) f(x)=x^2 / 4 + 9
f left parenthesis x right parenthesis equals Start Fraction x squared over 4 End Fraction plus 9

C) f(x)=x^2 / 4 − 9
f left parenthesis x right parenthesis equals Start Fraction x squared over 4 End Fraction minus 9

D) f(x)=x^2 / 36

Answer 1

B) f(x) = x^2/4 + 9

A vertical translation up 9 units adds 9 to the function value, so f(x) becomes x^2/4 + 9.
