None of the above
Multiply the bottom equation by 2, subtract out the y variable, solve for x
Graph both and find where they intersect
2
What is the first step in solving this equation?
Substitute the x in f(g(x)) with x^2-5
Set the two functions equal to each other
Solve g(x) for x and substitute it into f(g(x))
None of these options are correct
3
What is the first step in solving this equation:
multiply the whole equation by x
subtract 1/3 from both sides
multiply the whole equation by the lowest common denominator
divide the whole equation by the lowest common denominator
4
The x-intercept of a graph corresponds to what value?
f(0)
values of x such that f(x)=0
5
What is the end behavior of this graph?
y only increases without limit as x increases without limit
As x increases without limit, y decreases without limit
As x increases or decreases without limit, y increases without limit
As x decreases without limit, y decreases without limit
