Question

F(x) = 2x - 4 find f( 5 )

Answer 1

Answer:

f(5) = 2(5) - 4

f(5) = 10 - 4

f(5) = 6

Step-by-step explanation:

To find f(5), replace the x in the equation with its given value 5:

f(x) = 2x - 4

f(5) = 2(5) - 4

f(5) = 10 - 4

f(5) = 6

Answer 2

When the problem gives you f(5), it is basically telling you to plug in 5 into x in the equation so ...

f(5) = 2(5) - 4
f(5) = 10 - 4
f(5) = 6

Hope this helps!
