Answer:
The vertex is the point
Step-by-step explanation:
we know that
The equation of the absolute value in vertex form is equal to
where
a is a coefficient
(h,k) is the vertex
In this problem we have
so
---> the vertex represent a maximum
therefore
The vertex is the point
Answer:
4/3
Step-by-step explanation:
You can simplify the exponent expression using exponent rules. The rules are:
- A positive exponent is the number of times the base multiplies by itself.
- A negative exponent is the number of times the base divides itself.
- Multiplying same bases with exponents is simplified by adding the exponents.
- Dividing same bases with exponents is simplified by subtracting the exponents.
- A zero exponent always evaluates as 1.
The expression can be simplified first using the negative exponent rule to move base with negative exponent to the other part of the fraction.
Now use the multiplication rule to simplify numerator and denominator.
Finally, use the division rule to reduce the fraction.
