Answer:

f(x) = -3 when x = -1

Explanation:

Let's go through this!

So our equation is f(x) = 2x - 1

we are asked for the value of f(x) when x = -1

Let's consider this, the f(x) value is the y value

and the x value in f(x) is the x value

So when x = -1

what is the y value?

we can use the equation to subsitute -1 into x and solve for f(x)

f(x) = 2(-1)-1

f(x) = -3

Our answer is -3
