Question 1117167: The function is defined y two equations. The equation in the first row gives the output for negative numbers in the domain. The second row equation gives the output for non-negative numbers in the domain. Find the indicated function values
f(x) = 3x + 2 if x is less than 0
6x + 7 if x greater than or equal to 0
a) f(-6) b) f(0)
c) f(7) d) f(-100) + f(100)

a)-6%3C0 so f%28-6%29=3%28-6%29%2B2
b)0%3E=0 so f%280%29=6%280%29%2B7
c)7%3E=0 so f%287%29=6%287%29%2B7
d)-100%3C0 so f%28-100%29=3%28-100%29%2B2
100%3E0 so f%28100%29=6%28100%29%2B7
So,
f%28-100%29%2Bf%28100%29=3%28-100%29%2B2%2B6%28100%29%2B7
