Question

F(x) = 5x – 20 find f(6), f(10), and f(20)

Answer 1

f(6) = 10, f(10) = 30, f(20) = 80

Step-by-step explanation:

Plug in the values into the equation and compute. 5*6 - 20 = 10, 5*10 - 20 = 30, 5*20 - 20 = 80.

Answer 2

f(6) = 10

f(10) = 30

f(20) = 80

Step-by-step explanation:

Plug in the value

`\sf{f(x)=5x-20}`

`\sf{f(6)=5(6)-20}`

`\sf{f(6)=30-20}`

`\sf{f(6)=10}`

____________

`\sf{f(10)=5(10)-20}`

`\sf{f(10)=50-20}`

`\sf{f(6)=30}`

____________

`\sf{f(20)=5(20)-20}`

`\sf{f(20)=100-20}`

`\sf{f(20)=80}`

____________

Hence, these are the answers.
