Question

Given f(x)=3x-1 find f(-1)

Answer 1

Answer:

f( - 1) = - 4

Step-by-step explanation:

f(x) = 3x - 1

To find f(-1) substitute the value of x that's

- 1 into f(x). That's for every x in f(x) replace it with - 1 and solve

That's

f( - 1) = 3(-1) - 1

= - 3 - 1

We have the final answer as

f(-1) = - 4
