Question

Use only the digits 0 -9 and the decimal and the negative sign, if needed, to fill in the

blank.
If f(x) = 8x- 1, then f(3) =

Answer 1

To calculate f(3) for the function f(x) = 8x - 1, you substitute 3 for x, resulting in 8*3 - 1, which simplifies to 24 - 1, giving you 23.

Step-by-step explanation:

To find the value of f(3) when f(x) = 8x - 1, we need to replace x with 3 and perform the calculation.

• First, we replace x with 3: f(3) = 8(3) - 1.
• Next, we multiply 8 by 3: 8 * 3 = 24.
• Then, we subtract 1 from 24: 24 - 1 = 23.

Therefore, f(3) is 23.
