The value of f(7) when we substitute the value of x as 7 will gives negative 4. thus option A will be the correct choice.
What is a function?
Function is a type of relation, or rule, that maps one input to specific single output.
Functions which are formed by composing two or more functions in a way that one's output is another's input are called composite functions. They are also called function of functions.
It is Given that
f(x)=10-2x
We have to find the f(7). so we will substitute the value of x as 7.
f(x)=10-2x
f(7)=10-2(7)
f(7)=10-14
f(7)=-4
Therefore, the value of f(7) when we substitute the value of x as 7 will gives negative 4.
Thus option A will be the correct choice.
