Answer 2

To find the values of the given functions at specific points, you can simply substitute the given values of 'x' into each function.

1. For the function f(x) = 3x - 2: a) f(-1) = 3(-1) - 2 = -3 - 2 = -5 b) f(0) = 3(0) - 2 = 0 - 2 = -2 c) f(1) = 3(1) - 2 = 3 - 2 = 1 d) f(2) = 3(2) - 2 = 6 - 2 = 4

So, for this function: f(-1) = -5 f(0) = -2 f(1) = 1 f(2) = 4

2. For the function f(x) = 3/x + 5: a) f(-1) = 3/(-1) + 5 = -3 + 5 = 2 b) f(0) = 3/0 + 5 Note: Division by zero is undefined, and this function is not defined at x = 0.

c) f(1) = 3/1 + 5 = 3 + 5 = 8 d) f(2) = 3/2 + 5 = 1.5 + 5 = 6.5

So, for this function: f(-1) = 2 f(1) = 8 f(2) = 6.5

Please note that the function f(x) = 3/x + 5 is not defined at x = 0 as division by zero is undefined.
