Mathematics
1 answer:
bixtya [17]2 years ago
3 0

Answer:

0 < f(x) ≤ 3/4, or (0, 3/4]

Step-by-step explanation:

x² - x + 1 = x² - x + 1/4 + 3/4 = (x - 1/2)² + 3/4

It is always positive and has a minimum value of 3/4 at x = 1/2

So f(x) is always positive (not equal zero) and has a maximum value of 3/4

Then the range is 0 < f(x) ≤ 3/4, or (0, 3/4]

If you would like to solve -6 > -30 - 4x for x, you can do this using the following steps:

-6 > -30 - 4x
4x > -30 + 6
4x > -24      /4
x > -24/4
x > -6

The correct result would be x > -6.
