Algebra.Com's Answer #209040 by nerdybill(7384)![]() ![]() You can put this solution on YOUR website! A quadratic function is given below: \n" ); document.write( "f(x)=3x^2-x+6 \n" ); document.write( "What is f(2)? \n" ); document.write( "A. 40 \n" ); document.write( "B. 28 \n" ); document.write( "C. 16 \n" ); document.write( "D. 4 \n" ); document.write( ". \n" ); document.write( "f(x)=3x^2-x+6 \n" ); document.write( "f(x) is a \"function of x\" -- meaning for a particular value of x you can find the value of f(x). \n" ); document.write( "In your case, when they say \"what is f(2)\"? They are asking you what the value of f(x) when x=2. So, simply plug in the value of 2 for x and solve: \n" ); document.write( "f(x)=3x^2-x+6 \n" ); document.write( "f(2)=3(2^2)-2+6 \n" ); document.write( "f(2)=3(4)-2+6 \n" ); document.write( "f(2)=12-2+6 \n" ); document.write( "f(2)=10+6 \n" ); document.write( "f(2)=16 \n" ); document.write( " |
