Answer:
x = 1
Step-by-step explanation:
Given in the question the equation
y = -x² + 2x - 1
To find the x-intercept, substitute in 0 for y
0 = -x² + 2x - 1
To find value of x use quadratic equation
x = -b ± √b²-4ac / 2a
here a = -1
b = 2
c = -1
x1 = -2 + √2²-4(-1)(-1) / 2(-1)
= -2 + 0 / -2
= -2 / -2
= 1
x2 = -2 - √2²-4(-1)(-1) / 2(-1)
= -2 - 0 / -2
= -2 / -2
= 1

- Draw a number of spacing 0.25 each
- Start from -1 to 1
- -2/8 = -0.25 [mark on line]
- 3/6 = 0.5 [mark on line]
5.
- Midpoint of -2/5 and 1/2
- M = [-2/5 + 1/2] / 2
- M = [1/10] / 2
- M = 1/20
