Explanation of Solution
Given information:
The functionis
Formula Used:
Rational Zero Test.
The formula is:
To find the zeros of the function, substitute the function
Calculation:
The function is
To find the zeros of function, use the Rational Zero Test.
The leading coefficient is 1 and the constant term is
Put
Thus,
To simplify the function, take
Rewrite the above polynomial as:
To solve the above quadratic equation, split the middle term.
To find the zeros of the function, substitute the function
Rewrite it as:
That is,
Or
Or
Hence, the rational zeros of the function are

- 2. (5 points) Let f(x) = = - - - x² − 3x+7. Find the local minimum and maximum point(s) of f(x), and write them in the form (a, b), specifying whether each point is a minimum or maximum. Coordinates should be kept in fractions. Additionally, provide in your answer if f(x) has an absolute minimum or maximum over its entire domain with their corresponding values. Otherwise, state that there is no absolute maximum or minimum. As a reminder, ∞ and -∞ are not considered absolute maxima and minima respectively.arrow_forwardLet h(x, y, z) = — In (x) — z y7-4z - y4 + 3x²z — e²xy ln(z) + 10y²z.
