Use Lagrange quadratic polynomial to estimate the value of y at x = 1.5 from the data points (0, -1),(1, −1),(2, 7).

The windchill index announced during the winter by the weather bureau measures how cold it "feels" for a given temperature t (in degrees Fahrenheit) and wind speed w (in miles per hour). It is calculated by the formula C(t, w) = 35.74 + 0.6215t - 35.75w 0.16 + 0.4275tw0.16 + '.+ If the temperature is 31 degrees and the wind speed is 10 miles per hour, estimate the change in the windchill temperature if the wind speed increases by 4 miles per hour and the temperature drops by 5 degrees. (Round your answer to two decimal places.)

The regression in DESMOS using y₁ ~ Ax₁² + Bx₁ + C would try to find the best fit for the x₁/y₁ data table to what kind of function? A). Linear B). Absolute Value C). Quadratic
