1. The problem asks to find the value of the function $f(x) = 2x - 3$ at $x=1$. 2. The formula for evaluating a function at a given input is to substitute the input value into the function expression. 3. Substitute $x=1$ into $f(x)$: $$f(1) = 2(1) - 3$$ 4. Simplify the expression: $$f(1) = 2 - 3 = -1$$ 5. The value of $f(1)$ is $-1$, which is not listed among the options a, b, c, or d. Therefore, none of the given options (a. 1, b. -3, c. -2, d. 3) is correct for $f(1)$. Note: The second question about graphs is not answered as per instructions to solve only the first question.
