Chapter 9.3, Problem 22E

Demonstrate that the equation – 5x + |– 9y| = 10 does not represent a function by picking an input value of x for which there are at least two different corresponding output values of y. the chosen value for x, along with the two corresponding values of y below. Do not use a = 0. Enter Also, make sure all fractional answers are reduced.

Exercises 11-14: Sketch a graph of the function. 11. f(x) = -3x² + 3 12. g(x) = 2(x – 1)² – 3 13. f(x) = -|x + 3| 14. f(x) = V2 – x

There were around 70,000 black rhinos in the world in 1970. After that, their population declined by a rate of 12.6% annually. Which function best describes the number of black rhinos remaining x years after 1970?

In Exercises 24-25, find the domain of each function. 24. f(x) = V30 – 5x 25. g(x) = V3x – 15

Graph the function h (x) = ++3. 3 10- -10 -6 10 -10- - og

Evaluate the function to answer the question. Botanists have determined that some species of weed grow in a circular pattern. For one such species, the area A, in square meters, can be approximated by A(t) = 0.006nt^2, where t is the time in days after the growth of the weed first can be observed. Find the area (in square meters) this weed will cover 100 days after the growth is first observed. Round to the nearest square meter. ? m^2

explain this.    the given height of a spaceship at time x is defined by h(x)= ((-1/4x^6)+(16/5x^3)+7) at what time does the spaceship reach its maximum heights? how high does the spaceship go?

Evaluate the function to answer the question. Botanists have determined that some species of weed grow in a circular pattern. For one such species, the area A, in square meters, can be approximated by A(t) = 0.0067nt^2, where t is the time in days after the growth of the weed first can be observed. Find the area (in square meters) this weed will cover 100 days after the growth is first observed. Round to the nearest square meter. ? m^2
