Answer:g(x) = (x+3)/(x2-4)
The domain refers to all of the x values that the function can take on. In a rational expression like the one above, we have to be careful that the denominator is never 0, since division by 0 is undefined. We can factor the denominator of g(x) as follows:
g(x) = (x+3)/((x+2)(x-2)
The denominator will be zero when x = 2 or -2. Otherwise, g(x) is defined on all other values of x. So the domain of g(x) is "x = all x not equal to -2 or 2". In interval notation, the domain is:
(-∞,-2)U(-2,2)U(2,+∞)
On a number line, draw it as follows:
-∞ <======o=====o=======> +∞
-2 2
Step-by-step explanation:
(14 + 19 + x) / 3 = 17
(33 + x) / 3 = 17
33 + x = 17 * 3
33 + x = 51
x = 51 - 33
x = 18 <== third quiz grade
Answer:
20/16
Step-by-step explanation:
4 divided by 16 is 4. so that would mean 4 x 4 = 16, just apply that to 5 and you get 20 because 5x4 is 20.
7(q+8)
because () means multiply
so 7 TIMES Q + 8
if u like my answer please give me the brainiest because i really need it
