Given the recursively defined formula a1=−3 , an=an−1+4 , determine which option is the correct function notation.(1 point) Responses f(1)=−3; f(n)=an−1+4 f left parenthesis 1 right parenthesis equals negative 3 ; f left parenthesis n right parenthesis equals a subscript n minus 1 baseline plus 4 f(1)=−3; f(n)=f(n−1)+4 f left parenthesis 1 right parenthesis equals negative 3 ; f left parenthesis n right parenthesis equals f left parenthesis n minus 1 right parenthesis plus 4 a(1)=−3; f(n)=f(n−1)+4 a left parenthesis 1 right parenthesis equals negative 3 ; f left parenthesis n right parenthesis equals f left parenthesis n minus 1 right parenthesis plus 4 f(1)=−3; f(n)=f(an−1)+4
The correct function notation is:
f(1) = -3; f(n) = f(n-1) + 4
