If 2i is a zero of f(x)=x^4+x^2+a, find the value of a
Sedbober [7]

By the polynomial remainder theorem, because <em>x</em> = 2<em>i</em> is a zero of <em>f(x)</em>, we have no remainder upon dividing <em>f(x)</em> by <em>x</em> - 2<em>i</em>.

Computing the quotient yields

\dfrac{x^4+x^2+a}{x-2i} = x^3+2ix^2-3x-6i+\dfrac{12+a}{x-2i}

Then if the remainder term is 0, follows that <em>a</em> = -12.

What are the domain,range, and asymptote of h(x)=2x + 4
GREYUIT [131]
This is a linear function, so there is NO asymptote.  The slope is 2 and the y-intercept is 4.  Since this is a polynomial, the domain is "the set of all real numbers," and the range is also that.
