Answer:
8
Step-by-step explanation:
-x² + 4x -2 = 0
discrimination for ax² + bx + c =0 is b² - 4ac
4² - 4 x (-1) x (-2) = 8
The answer is 25
50% × 50 = (50/100) × 50 = 25
So
remember
translates to
basically, the power that a must be raised to to obtain c is b
so
translates to

Hope this helps <3
Note that f(1) = 6(1)+2 = 8. Next, evaluate g(x) at x=8: g(f(1)) = g(8) = 2(8) + 4/5, or 16 4/5.
