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→+∞

Answer:
C) Both
Step-by-step explanation:
The given equation is:
To solve the given equation, we can use the Zero Product Property according to which if the product <em>A.B = 0</em>, then either A = 0 OR B = 0.
Using this property:
So, Erik's solution strategy would work.
Now, let us discuss about Caleb's solution strategy:
Multiply i.e.
=
So, the equation becomes:
Comparing this equation to standard quadratic equation:
a = 3, b = -10, c = -8
So, this can be solved using the quadratic formula.
The answer is same from both the approaches.
So, the correct answer is:
C) Both
