Answer:
option C and F
Step-by-step explanation:
Given excluded value is x=-5
Excluded value are the values that makes the denominator 0
Now we check out each option and see , in which option the denominator becomes 0 when x=-5
When denominator has (x+5) then when we plug in x=-5
(x+5) becomes (-5+5) =0
So we look at the options that has factor (x+5) in the denominator
In option C we have x^2 -25
When we plug in -5 for x then it becomes (-5)^2 - 25 =0
So x=-5 makes the denominator 0
-5 is an excluded value for option C
Last option f has x+5 in the denominator
x=-5 make the denominator 0
so , -5 is an excluded value for option F
Answer:
x=-12
Step-by-step explanation:
Start by getting all of the x values on one side and other to the other.
1/3x-3/4x=1+4
Now simplify. Because 1/3 and 3/4 do not have the same denominator, find the least common factor between 3 and 4 (which is 12) and make the fractions have denominators of 12.
4/12x-9/12x=5
-5/12x=5
x=5*(12/-5)=60/-5=-12
x=-12
Answer:
So the answer is A
Step-by-step explanation:
A)

f(1) = 1124.74
f(2)= 1552.143
f(3) = 2141.9575
f(4)= 2955.901
f(5)= 4079.1439
So the answer is A
B)

f(1) = 813.77
wrong!
C)

f(1) = 816.14
D)

f(1)= 813.65
wrong!
