Answer:
To solve for the zeros of the function equate f(x) = 0
That's
- 2x² + x + 5 = 0
Using the quadratic formula
a = - 2 b = 1 c = 5
And from the question
b² - 4ac = 41
So we have
We have the final answer as
Hope this helps you
Answer:
7
Step-by-step explanation:
First, you wrote -3x-7<20, that means -3x<20+7
or -3x<27 and we have x>-9
We draw the line of equation x= -9 and we have the set of solution is the haft of the plan on the right of the line x= -9
