What is the value of 5x^2 − 1.9x − 3.7 for x = − 0.3?  Options
A) −4.72  B) −3.82  C) −3.58  D) −2.68  E) 0.57
5x^2 - 1.9x - 3.7, x =-0.3   Firstly, 5x^2 can be written as 5 * x * x - substituting one of the x with -0.3   We have -1.5x - 1.9x -3.7 ---&gt; -3.4x-3.7 ---&gt; -3.4 (-0.3) -3.7 ---&gt; 1.02 - 3.7 = -2.68   ANSWER:−2.68
