Answer:
[tex]f(x) = 7x - 8[/tex] or
[tex]y = 7x - 8[/tex]
Step-by-step explanation:
Let x be the input and f(x) or y represent output.
The function in this case is given as firstly we will take seven times of the input and subtract eight to it, to obtain the required output.
[tex]y = 7x - 8\\or\\f(x) = 7x - 8[/tex]
