Question

If f(x) = 6x² - 4 and g(x) = 2x + 2, find (f- g)(x)

Answer 1

Step-by-step explanation:

$f(x) = 6 {x}^{2} - 4$

$g(x) = 2x + 2$

$\:$

$= (f - g)(x)$

$= f(x) - g(x)$

$= 6 {x}^{2} - 4 - (2x + 2)$

$= 6 {x}^{2} - 4 - 2x - 2$

$= 6 {x}^{2} - 2x - 4 - 2$

$= 6 {x}^{2} - 2x - 6$

$(f - g)(x) = 6 {x}^{2} - 2x - 6$
