Graph
$y = 2 ^ { x + 2 } + 2 ^ { x + 1 } + 2 ^ { x }$
$y = 224$
$y$Intercept
$\left ( 0 , 7 \right )$
$x = 5$
Solve the equation
$\color{#FF6800}{ 2 } ^ { \color{#FF6800}{ x } \color{#FF6800}{ + } \color{#FF6800}{ 2 } } \color{#FF6800}{ + } \color{#FF6800}{ 2 } ^ { \color{#FF6800}{ x } \color{#FF6800}{ + } \color{#FF6800}{ 1 } } \color{#FF6800}{ + } \color{#FF6800}{ 2 } ^ { \color{#FF6800}{ x } } = \color{#FF6800}{ 224 }$
$ $ Substitute $ 2 ^ { x } $ with $ X $ and solve $ $
$\color{#FF6800}{ 2 } ^ { \color{#FF6800}{ x } } = \color{#FF6800}{ 32 }$
$\color{#FF6800}{ 2 } ^ { \color{#FF6800}{ x } } = \color{#FF6800}{ 32 }$
$ $ Solve the exponential equation (inequality) by unifying the bases of the exponents $ $
$\color{#FF6800}{ x } = \color{#FF6800}{ 5 }$
