Answer:
Step-by-step explanation:
In the expressions, the value at which the domain of the function will be the set of all real numbers except x=4.1 is the value at which 4.1 makes the denominator equal to zero, i.e makes the fraction undefined.
Given the options
Setting the denominator to zero, x-4.1=0, x=4.1. The fraction is undefined at x=4.1
Setting the denominator to zero, x+4.1=0, x=-4.1. The fraction is undefined at x=-4.1
Setting the denominator to zero, x-2.8=0, x=2.8. The fraction is undefined at x=2.8
Setting the denominator to zero, x-2.5=0, x=2.5. The fraction is undefined at x=2.5
Therefore, function that has a domain of all real numbers except x=4.1 is:
Answer:
Step-by-step explanation:
Since the general quadratic equation is,
Here the given table is,
x 1 2 3 4 5 6 7
y 5.9 8.9 13.4 20.1 30.1 45.1 67.7
By the graphing calculator,
a = 1.87024 ≈ 1.87
b= -5.15833 ≈ -5.15
c = 10.5429 ≈ 10.54
By putting the values of a, b and c,
The required quadratic equation is,
⇒ First Option is correct.
