I’ll give grainiest for right answer

Select the quadratic that has root x = 8 and x = -5

Write the sine and cosine values of a, b, respectively, in the figure for (1) and (2) + explanation.

Given the quadratic function f(x)=3x^2-24x+49 a. use “completing the squares” to convert the quadratic function into vertex form b. state the vertex c. find the x and y intercepts d. graph the function
