Week 4

Richard, Leo, and Betty are triplets. They were born 4 years after their sister, Kennedy, and 3 years before their sister, Mya. If we let x represent the age of Richard, Leo, and Betty, which polynomial represents the product of all 5 ages?

The x-intercept of y=-2\sqrt{x+4}+3 to the nearest hundredth is___

Use graphing technology to solve the following equation. Select the correct solution/s.

\frac{x-3}{x+2}=1-\frac{x^{2}-9}{x+3}

For what values is the graph of y=f(x) be equal to y=\sqrt{f(x)} ?

f(x)=0.75x

The domain of the function y=\frac{3x}{x^{2}+2x-8} is___

If g(x)=-2(x-a)^{2}(x-b) where 0<a<b , then the domain of y=\sqrt{g(x)} is____

A radical function of the form y=a\sqrt{x-h}+k had domain [x|x≥4, x∈R] and range [y|y≥-2, y∈R]. If the graph of the function passes through the point (13,16) then the value of a is____
