Diketahui F (X)= 8×2+X+5G(X)= 7x – 1Tentukan = (3F/2G) (-1)

Penjelasan dengan langkah-langkah:

$f(x) = 8 {x}^{2} + x + 5$

$g(x) = 7x - 1$

$( 3f div 2g)( - 1) = ...$

$( 3f div 2g)( x) = frac{3(8 {x}^{2} + x + 5)}{2(7x - 1)}$

$( 3f div 2g)( x) = frac{24{x}^{2} + 3x +15}{14x - 2}$

$( 3f div 2g)( - 1) = frac{24{ (- 1)}^{2} + 3( - 1)+15}{14( - 1) - 2}$

$( 3f div 2g)( -1) = frac{24 - 3 +15}{ - 14 - 2}$

$( 3f div 2g)( -1) = frac{36}{ - 16}$

$( 3f div 2g)( -1) = - frac{9}{ 4} = - 2frac{1}{4}$

$( 3f div 2g)( - 1) = - 2.25$
