Answer:
{4, - 1}
Step-by-step explanation:
Given
2y² - 6y - 8 = 0 ← in standard form
with a = 2, b = - 6, c = - 8
Using the quadratic formula to solve for y
y = ( - (- 6) ± ) / (2 × 2)
= ( 6 ± ) / 4
= ( 6 ± ) / 4
= ( 6 ± 10 ) / 4
x = =
= 4
OR
x = =
= - 1
Solution is { 4, - 1 }
Answer:
(–∞, –3)
Step-by-step explanation:
The function is a quadratic function of order 2 and positive coefficient.
This is in the form of the function , but it is displaced 3 units to the left of the x axis and two units up in the y axis. type of functions are decreasing from -∞ to its vertex and then they are increasing from the vertex to infinity.
Observe in the attached graph that this function has its vertex in the point (-3, 2) and is decreasing from -∞ to x = -3. Then it is increasing until ∞. Therefore the correct option is:
(-∞, -3)
