Question

1) Given the function f(x) = 2x -3, evaluate f(3).

Answer 1

Answer:

1) $f(3) = 3$

2) $x = 2$

Step-by-step explanation:

Given:

$f(x) = 2x -3$

Evaluating $f(3)$:

$f(3) = 2(3) -3 \\ f(3) = 6 -3 \\ f(3) = 3$

Solving for $f(x) = -1$:

$2x -3 = 1 \\ 2x -3 +3 = 1 +3 \\ 2x = 4 \\ \frac{2x}{2} = \frac{4}{2} \\ x = 2$
