The product of two functions $(fg)(x)$ means you multiply their output values together at the same input. So to find $(fg)(1)$, you need to read the $y$-value of each graph at $x = 1$, then multiply those two values. It's a straightforward application of function composition notation—just remember you're multiplying the outputs, not composing them.
