Question

If f(x) = 7(x-1) + 8 , what is rhe value of f(11) ?​

Answer 1

F(11) = 78

Explanation:

f(11) means that you would just have to replace “x” on the equation with 11 and then solve;

=> f(11) = 7(11 - 1) + 8

=> f(11) = 7(10) + 8

=> f(11) = 70 + 8

=> f(11) = 78

therefore the answe is 78

Hope this helps!

Answer 2

f(11)=78

Explanation:

f(11)=7(11-1)+8

f(11)=77-7+8

f(11)=78
