Describe the end behavior of F(x) = x^2 + 4x +3
1 answer:
Answer:
see the explanation
Step-by-step explanation:
we know that
The end behavior of a polynomial function is the behavior of the graph of f(x) as x approaches positive infinity or negative infinity.
The degree and the leading coefficient of a polynomial function determine the end behavior of the graph
In this problem
we have
Is a vertical parabola open upward (the vertex is a minimum)
The degree of the function is even (2) and the leading coefficient is positive.
So,
the end behavior is:
f(x)→+∞, as x→−∞
f(x)→+∞, as x→+∞

It is given in the question that
Ms. Velez will use both x gray bricks and y red bricks to build a wall around her garden. Gray bricks cost $0.45 each and red bricks cost $0.58 each. She can spend up to $200 on her project, and wants the number of red bricks to be less than half the number of gray bricks.
Maximum she can spend is $200. That is
And
And that's the required inequalities .
