Question
las funciones f y g se definen a continuación.
$f(x)=4x - 3$ $g(x)=-4x^{2}-3$
hallar $f(-3)$ y $g(4)$.
simplificar las respuestas tanto como sea posible.
$f(-3)=\square$
$g(4)=\square$
Step1: Calculate \( f(-3) \)
Substitute \( x = -3 \) into \( f(x) = 4x - 3 \).
\( f(-3) = 4(-3) - 3 \)
\( = -12 - 3 \)
\( = -15 \)
Step2: Calculate \( g(4) \)
Substitute \( x = 4 \) into \( g(x) = -4x^2 - 3 \).
\( g(4) = -4(4)^2 - 3 \)
\( = -4(16) - 3 \)
\( = -64 - 3 \)
\( = -67 \)
