The number of accidents in 1 month involving drivers x years of age in a certain country can be approximated by the function f (x) = 3x2 - 150x + 2,000.
Find the number of accidents in 1 month that involved 47 olds.

Q_2 Match the description with the correct symbolic expression.
a line with a negative slope
f(x) = 2x -4
2x + 9y = -5
x = -4
y = -5

Q_3 Evaluate as indicated.
