Given the function f(x)=2x^2-8x+3, answer the following questions using specific language to explain each step performed.
\n" ); document.write( "----------------------------
\n" ); document.write( "1.)determine the nature of the roots, using the discriminant.
\n" ); document.write( "discriminant = b^2-4ac
\n" ); document.write( "d = 8^2-4*2*3 = 64 - 24 = 40 > 0
\n" ); document.write( "Since d>0, the function has two unequal Rean Number solutions.
\n" ); document.write( "----------------------------------------
\n" ); document.write( "2.) solve by using the quadratic formula
\n" ); document.write( "x = [8 +- sqrt(40)]/4
\n" ); document.write( "x = 2 +- (1/2)sqrt(10)
\n" ); document.write( "-------------------------------
\n" ); document.write( "3.) graph using vertex roots and direction
\n" ); document.write( "Vertex occurs at x=-b/2a = 8/4 = 2
\n" ); document.write( "f(2) = 8-16+3 = -5
\n" ); document.write( "Vertex: (2,-5)
\n" ); document.write( "Direction:Since the coefficient of x^2 is positive, the parabola opens up.
\n" ); document.write( "\"graph%28400%2C300%2C-10%2C10%2C-10%2C10%2C2x%5E2-8x%2B3%29\"
\n" ); document.write( "------------------------
\n" ); document.write( "4,)what is the minimum?
\n" ); document.write( "y=-5
\n" ); document.write( "maximum?
\n" ); document.write( "There is no maximum as the parabola opens up.
\n" ); document.write( "---------------------------
\n" ); document.write( "5.) what is the axis of symmetry?
\n" ); document.write( "The vertical line thru the vertex: x=2
