Answer:
Consider the exponential function
-----------(1)
and when it is reflected across y axis , it's equation becomes
--------------------------(2)
As, domain of a function is defined as the set of all values of x , for which y is defined.
So, for function 1, domain is set of all real numbers.That is , x∈[-∞ ,∞]
And for function 2, which is reflection of function 1, it's domain will also be set of all real numbers.That is , x ∈ [-∞, ∞]
So, Simon is correct between Alissa and himself, as he is saying if an exponential function is reflected across the y-axis, the domain will still be all real numbers is true statement.
Answer:
Step-by-step explanation:
you have a total of 5+7+4=16 marbles in the box.
5 are red
7 are white
4 are green
If you randomly select 1 marble out of the box, the probabilities are:
5/16 chance of being red
7/16 chance of being white
4/16 chance of being green
Answer:
f(2) = 3
Step-by-step explanation:
Substitute 2 for x, and evaluate the expression.
f(x) = 2x - 1
f(2) = 2(2) - 1
f(2) = 4 - 1
f(2) = 3
