This is what I got, but you might want to double check me because I'm not that good at math (this is what I got for the discontinuity);
1. f(x)= x^2+6+8/x+4
*x+4=0
-4 -4
x= -4
This means that x cannot equal -4
2. f(x)= (x+2)(x-4)/(x+2)(x+2)
*Note: When I did my calculations, I cancelled out all (x+2) binomials except for one in the denominator*
f(x)= x-4/x+2
*x+2=0
-2 -2
x= -2
This means x cannot equal -2
*You may want to check my work, but I believe that your answer is going to be either C or D. Personally, I assume it's C, but that's just me. Anyway, it's probably going to be C or D, or at least that's what I think.*
<span>Residual value is the difference between the observed value of the dependent variable (y) and the predicted value (ŷ) in a data set.
i.e. Residual value = given value - predicted value
From the table, the residual value corresponding to a has 4.1 as the given value and 4.5 as the predicted value.
Therefore, a = 4.1 - 4.5 = -0.4
Similarly, </span><span>the residual value corresponding to b has 7.2 as the given value and 7.05 as the predicted value.
Therefore, b = 7.2 - 7.05 = 0.15
</span>
Therefore, a = -0.4 and b = 0.15
Answer:
a 73.75
Step-by-step explanation:
to find the original price you would divide 59.00 by 80%
