Question

Determine the values (a) f(-3) (b) f(1),and (c) f(4) in each of the following functions.

f(x) =2x

Answer 1

The function f(x) = 2x evaluates to f(-3) = -6, f(1) = 2, and f(4) = 8. We obtain these values by substituting x with -3, 1, and 4 in the function, respectively.

Step-by-step explanation:

To determine the values of the function f(x) = 2x at different values of x, we can simply substitute the given values of x into the function and calculate the results.

1. f(-3): We substitute x with -3. f(-3) = 2(-3) = -6.
2. f(1): We substitute x with 1. f(1) = 2(1) = 2.
3. f(4): We substitute x with 4. f(4) = 2(4) = 8.

The values for f(x) at -3, 1, and 4 are -6, 2, and 8, respectively.
