Determine a quadratic function f(x) = ax^2 + bx + c such that the maximum value of the function is 2 and the graph of the function has x-intercepts of 3 and 5.
A) f(x) = x^2 − 8x + 15
B) f(x) = 2(x^2 − 8x + 15)
C) f(x) = −2(x^2 − 8x + 15)
D) f(x) = −2(x^2 − 8x − 15)

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
