4. Which of the following values of x will make the inequality x+3x+2 < Otrue? A. x= -2 B. x=0 C....

it's B.

Step-by-step explanation:

First solve f(x) = x^2 - 3x + 2 = 0

Since (a + b + c = 0), use the Shortcut. The 2 real roots are x = 1 and x = c/a = 2.

Use the algebraic method to solve f(x) > 0. Since a > 0, the parabola opens upward. Inside the interval (1, 2), f(x) is negative. Outside the interval (1, 2), f(x) is positive.

answer by open intervals: (-infinity, 1) and (2, +infinity)

graph{x^2 - 3x + 2 [-10, 10, -5, 5]}

answer: quantity is refders to the numbers of sized shapes and express the numbers at all times.

step-by-step explanation:

he drives at 300 km per hour so the answer is 300km/hr
