The sum of the roots of 3x 2 + 11x - 4 = 0 is<br><br> -11/3<br> -4/3<br> 11/3<br> 4/3
givi [52]

Answer:

The correct option is 1.

Step-by-step explanation:

If a quadratic equation is defined as

ax^2+bx+c=0             .... (1)

Then the sum of the roots is -b/a and the product of roots is c/a.

The given equation is

3x^2+11x-4=0          ... (2)

From (1) and (2) we get a=3, b=11 and c=-4.

The sum of roots is

\frac{-b}{a}=-\frac{11}{3}

The sum of roots is -\frac{11}{3}.

Therefore the correct option is 1.

Graph the function. Describe its position relative to the graph of the indicated function
sweet [91]

Answer:

C

Step-by-step explanation:

If the parent function is function y=f(x) and a>0, then

  • the graph of the function y=f(x-a) is translated a units to the right graph of the parent function;
  • the graph of the function y=f(x+a) is translated a units to the left graph of the parent function;
  • the graph of the function y=f(x)+a is translated a units up graph of the parent function;
  • the graph of the function y=f(x)-a is translated a units down graph of the parent function.

In your case, the grapgh of the function y=2^x+2 is translated 2 units up the graph of the function y=2^x.
