Y=a(x-h)^2+k
is what vertex form look like. (h,k) is your vertex so in this problem your vertex would be (60,200)
Answer:
-3(4 - 6x)
-12 +18x
=18x - 12
Step-by-step explanation:
You multiple the negative 3 with positive 4 to get negative 12.
An you also multiple the negative 3 with negative 6x (a negative multiple a negative changes into positive) giving you 18x as your answer
Answer:
y = |x|
Step-by-step explanation:
Since it's absolute value, number will turn out positive
Answer:
.
For values of x>0, it can be rewritten as 
Step-by-step explanation:
For the expression:

We can apply this logarithmical property: 
Then,

If we assume values of <em>x </em>> 0 (non negative values for x), then the expression could be rewritten as follows:
, since 
We have to remember that <em>domain</em> (all possible values x) for logarithmic function is for all x > 0, or mathematically expressed as:
Domain:
