Question 1036510
.
Let {{{f(x) = 4x^2 + 11x - 3}}} 

<pre>
A)  find the roots. {{{x[1]}}} = {{{1/4}}}, {{{x[2]}}} = -3.   Use the quadratic formula.

B)  factor f.       f(x) = (4x-1)*(x+3)

C)  sketch f

D) solve f(x) > 0.  x < -3  and/or  x > {{{1/4}}}.  In the interval form ({{{-infinity}}},-3) U ({{{0.25}}},{{{infinity}}})
