Find the number of real number solutions for the equation. x^2 - 3x + 8 = 0
a) 2
b) 0
c) cannot be determined
d) 1

0

Step-by-step explanation:

Read off the coefficients of this quadratic polynomial x^2 - 3x + 8 = 0:

a = 1, b = -3, c = 8.

Now calculate the discriminant, b² - 4ac:

(-3)² - 4(1)(8) = 9 - 32 = -23

Because the discriminant is negative, the two roots will be complex.  There are no real roots.  Correct answer is B (0).

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
