Question

Consider the function f(x)= -2x + 5 what is f(1) enter your answer as simplified fraction in the box

Answer 1

To find f(1) for the function f(x) = -2x + 5, substitute 1 for x to get f(1)=-2(1)+5, which simplifies to f(1)=3.

Step-by-step explanation:

The question asks us to evaluate the function f(x) = -2x + 5 at x = 1. Here's how to do it:

1. Substitute the value of x with 1 in the function: f(1) = -2(1) + 5.
2. Multiply -2 by 1: -2 * 1 = -2.
3. Add 5 to -2: -2 + 5 = 3.

Therefore, the value of f(1) is 3, which is already a simplified fraction (3/1).

Answer 2

f(x) = -2x + 5
is a function, therefore,
x is an input and y is an output.
So, to solve it, just substitute x in.

f(1) = -2(1) + 5
f(1) = 3
