Answer:
see explanation
Step-by-step explanation:
Note that (x² + 5)(x² - 5) are the factors of a difference of squares
a² - b² = (a + b)(a - b)
with a = x² and b = 5, hence
(x² + 5)(x² - 5) = (x²)² - 5² = - 25, thus
3( - 25) = 3 - 75
what is the value of g(-4) when g(x)=3x-5
Given g(x) = 3x -5
To find g(-4) we replace x with -4 in g(x) = 3x -5
g(x) = 3x -5
g(-4) = 3(-4) -5= -12 -5 = -17
the value of g(-4) = -17
The steps are:
1 : g(x) = 3x -5
2 : Replace -4 for x
3: g(-4) = 3(-4) -5
4 : g(-4) = -12 -5
5: g(-4) = -17
the value of g(-4) = -17
