Domain are all the possible x values of a function. When you look at a cosine graph you can see that it goes on into infinity in the x or horizontal direction. This means that all x values are included in cosine. Because of this the domain is:
all real numbers
or
(-∞,∞)
^^^ It can be written both ways
Hope this helped! Let me know if there is anything else I can do!
Answer:
No. It is a constant function.
Step-by-step explanation:
The function f(x) = e^2 is not an exponential functional. Rather, it is a constant function. The reason for this is that in f(x) = e^2, there is no x involved on the right hand side of the equation. The approximate value of e is 2.718281, and the approximate value of 2.718281^2 is 7.389051. This means that f(x) = e^2 = 7.389051. It is important to note that for any value of x, the value of the function remains fixed. This is because the function does not involve the variable x in it. The graph of the function will be a line parallel to the x-axis, and the y-intercept will be 7.389051. For all the lines parallel to x-axis, the value of the function remains the same irrespective of the value of x. Also, the derivative of the function with respect to x is 0, which means that the value of the function is unaffected by the change in the value of x!!!
Distributive because they are multiplying a number by a group of numbers added together is the same as doing each multiplication separately.
Divide both sides of the inequality by 5 to give an answer of a - 5 > 5. Group all the variables and constants to opposite sides of the inequality. For this given,
a > 5 + 5
which simplifies into a > 10. Thus, the answer is the fourth choice.
Answer:
hello : (x+3)² -2 = 0
Step-by-step explanation:
x²+12x+7=0
(x² +12x +9) -2 =0
(x+3)² -2 = 0....an equation equivalent
