Answer:
The domain of a function is the complete set of possible values of the independent variable. The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.
Step-by-step explanation:
When finding the domain, remember:
The denominator (bottom) of a fraction cannot be zero
The number under a square root sign must be positive in this section
The range is the resulting y-values we get after substituting all the possible x-values.
The volume of a cylinder with a radius of 9 cm and a height of 22 cm is 5598.32
Answer:
Step-by-step explanation:
(x + 2)(x +9)= x*(x +9) + 2*(x +9)
= x*x + x*9 + 2*x + 2*9
= x² +<u> 9x + 2x </u>+ 18 {Combine like terms}
= x² + 11x +18
C.
Notice that both sides point towards infinity. This means that it is an even degree. Also, it crosses the x axis twice, which makes it have 2 real zeroes.
