If f(x)= x2 – 3, then f(a-b) in standard
form is equivalent to:

Answer 1

`\huge \bf༆ Answer ༄`

We have to find : f (a - b) = ?

`{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:f(x) = {x}^(2) - 3`

`{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:f(a - b) = (a - b) {}^(2) - 3`

`{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:f(a - b) = {a}^(2) + {b}^(2) - 2ab - 3`
