SOLUTION: I am having trouble with the following problem: Let f(x) {= 3x^2 - x+1, x < 5 -4x-3, x>5 (the arrow is underscored) a) f(6) b f(0) c) f(-3)

Question 245428: I am having trouble with the following problem:
Let f(x) {= 3x^2 - x+1, x < 5
-4x-3, x>5 (the arrow is underscored)
a) f(6)
b f(0)
c) f(-3)

Answer by dabanfield(803) (Show Source): You can put this solution on YOUR website!
Since 6 is greater than 5 use f(x) = -4*x-3
f(6) = -4*6 - 3 = ?
Since 0 is less than 5 use f(x) = 3x^2 - x + 1
f(0) = 3*(0^2) - 0 + 1 = ?
Since -3 is less than 5 use f(x) = 3x^2 - x + 1
f(-3) = 3*(-3)^2 - (-3) + 1 = ?
