Step 1 :Given the polynomials $f(x)=4 x^{4}+5 x-4$, $g(x)=4 x^{4}+2 x$, and $h(x)=4 x^{4}+6$.
Step 2 :Identify the degree of the polynomials. The degree of a polynomial is the highest power of x in its expression. All three polynomials are of degree 4.
Step 3 :Identify the leading coefficient of the polynomials. The leading coefficient is the coefficient of the term with the highest power. All three polynomials have a leading coefficient of 4.
Step 4 :Identify the long-run behavior of the polynomials. The long-run behavior of a polynomial refers to the behavior of the polynomial as x approaches positive or negative infinity. For all three polynomials, as $x$ goes to $+\infty$, the function goes to $+\infty$ and as $x$ goes to $-\infty$, the function goes to $+\infty$.
Step 5 :Identify the number of terms in each polynomial. The polynomials $f(x)$, $g(x)$, and $h(x)$ have 3, 2, and 2 terms respectively.
Step 6 :Identify the x-intercepts of the polynomials. The x-intercepts are the values of x for which the polynomial equals zero. The x-intercepts for the polynomials are complex numbers, which means they do not intersect the x-axis in the real number plane. However, the number of x-intercepts (including complex ones) is different for each polynomial.
Step 7 :Identify the y-intercepts of the polynomials. The y-intercept is the value of the polynomial when x=0. The y-intercepts for the polynomials $f(x)$, $g(x)$, and $h(x)$ are -4, 0, and 6 respectively.
Step 8 :From the above analysis, we can conclude that the similarities between the polynomials are: For each, as $x$ goes to $+\infty$, the function goes to $+\infty$. They are all degree 4 polynomials. For each, as $x$ goes to $-\infty$, the function goes to $+\infty$. They all have a leading coefficient of 4.
Step 9 :The differences between the polynomials are: They have a different number of terms. They have different $x$-intercepts. They have different $y$ intercepts.
Step 10 :\(\boxed{\text{Similarities:}}\) \(\boxed{\text{A. For each, as } x \text{ goes to } +\infty, \text{ the function goes to } +\infty.}\) \(\boxed{\text{B. They are all degree 4 polynomials.}}\) \(\boxed{\text{C. For each, as } x \text{ goes to } -\infty, \text{ the function goes to } +\infty.}\) \(\boxed{\text{D. They all have a leading coefficient of 4.}}\)
Step 11 :\(\boxed{\text{Differences:}}\) \(\boxed{\text{A. They have a different number of terms.}}\) \(\boxed{\text{B. They have different } x \text{-intercepts.}}\) \(\boxed{\text{C. They have different } y \text{ intercepts.}}\)
