Consider the function:

f(x)=5x+40

To calculate f(x) when x=-5

Substitute x=-5 in given function then,

f(−5)=5(−5)+40

=−25+40

=15

Hence the value of the function is 15 when x=-5

f(x)=5x+40

To calculate f(x) when x=-5

Substitute x=-5 in given function then,

f(−5)=5(−5)+40

=−25+40

=15

Hence the value of the function is 15 when x=-5
