This is not my pic because I forgot to screenshot it when I did it. Microsoft has the hardest captcha I have ever had to complete. This one looks easier but I had a similar one that on my phone the images were too small, not recognizable and were more abstract looking shapes. It was so hard, I failed like 8 times (there were several ‘rounds’) and it almost made me second guess whether I might actually be a robot lol. Luckily, there was an audio version where you have to pick from a number of melody recordings and choose the one that was a pattern. Anyone else have trouble with this?

    I agree with your solution! GG

    • f’(x) = 3(13)x²+2(11)x+10
    • f"(x) = 6(13)x+22 = 72x + 22
    • f"(52) = 4056 + 22 = 4 078

    4078 + 52 = 4 130
