Can someone me solve this? i don't know what i am doing wrong. i need to complete the square to find the vertex. show me how you do it. f(x) = −x2 + 2x − 3

f(x) = -x² + 2x - 3

f(x) = -(x² - 2x) - 3

f(x) = -(x² - 2x + 1) - 3 - -1

f(x) = -(x-1)² - 2

x = -2

y = 848

step-by-step explanation:

plug in the numbers

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.
