Question

F(x)=2x+1, find f(-5)

Answer 1

To find f(-5) for the function f(x)=2x+1, simply substitute x with -5 to get f(-5) = 2(-5) + 1, which simplifies to f(-5) = -9.

Step-by-step explanation:

To find f(-5) for the function f(x) = 2x + 1, we simply substitute x with -5 in the equation and calculate the result. The process is a straightforward example of evaluating functions at specific points.

The calculation would be as follows:

f(-5) = 2(-5) + 1

= -10 + 1

= -9

So, f(-5) equals -9. This evaluation process is fundamental in algebra and helps in understanding how a function behaves at given input values. Therefore, the value of f(-5) is -9.
