(f+g)(x) is simply saying add these two problems together.
(2x+6) + (4x^2)
Parenthesis are now useless, as there is only addition.
2x + 6 + 4x^2
Reorder, cause it's pretty and familiar
4x^2 + 2x + 6
We could further simplify
2(2x^2 + x + 3)
Answer:
Step-by-step explanation:
The null hypothesis is usually the default statement. The alternative is the opposite of the null and usually tested against the null hypothesis
In this case study,
The null hypothesis in would be that the mean time between clicks of the second hand on a particular clock is 1 second. In symbolic form it would be u = 1
The alternative hypothesis would be that the mean time between clicks of the second hand on a particular clock is 1 not second. In symbolic form, it would be: u =/ 1
Answer:
Option C. (-x,y)
Step-by-step explanation:
we know that
A point reflected across the y-axis has the following rule
(a,b)------> (-a,b)
so
If the center of the original circle was located at (x, y)
then
the center of the new circle after the transformation will be (-x,y)
restrict the domains of quadratic functions and absolute value functions, because these functions are
functions. For instance, the quadratic function f(x) = x^2 pairs both −2 and 2 with 4, and the absolute value function f(x) = |x| pairs both −2 and 2 with 2.
Linear functions (excluding constant functions) and exponential functions are
functions, so their domains
to be restricted.
_________________
An absolute value function, without domain restriction, has an inverse that is NOT a function.
In order to guarantee that the inverse must also be a function, we need to restrict the domain of the absolute value function to make it a one-to-one function.
