To find $(f \cdot g)(1)$, first evaluate $f(1)$ and $g(1)$, then multiply the results. $f(1) = 4(1) - 7 = -3$ and $g(1) = -2(1) + 9 = 7$. Multiplying these gives $-3 \cdot 7 = -21$.

Let f(x)=4x−7 and g(x)=−2x+9f ( x ) = 4 x - 7 \text { and } g ( x ) = - 2 x + 9f(x)=4x−7 and g(x)=−2x+9

Let $f ( x ) = 4 x - 7 \text { and } g ( x ) = - 2 x + 9$
