Which of the following is a solution of x2 + 2x + 4? a) −2 + two i times the square root of 3 b) 2 + two i times the square root of 3 c) 1 − i times the square root of 3 d) −1 + i times the square root of 3

The correct option is D) −1 + i times the square root of 3.

Step-by-step explanation:

We are given the following expression and we are to find the solutions for this quadratic expression:

Since we cannot factorize this so we will use the quadratic formula to solve it:

Therefore, from the given answer options the correct option is D) −1 + i times the square root of 3.

the answer is 175.4379

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
