Question

If f(x)= { -3x if x<-1

0 if x=-1

2x²+1 if x>-1

Find: a. f(-2) b.f(-1) c. f(0)

Answer 1

f(x) = -3x if x < -1

f(x) = 0 if x = -1

f(x) = 2x^2 + 1 if x > -1

find f(-2), f(-1) and f(0)

f(-2) = -3x = -3(-2) = 6

f(-1) = 0

f(0) = 2x^2 + 1 = 2(0)^2 + 1 = 0 + 1= 1

f(0) = 1

f(-2) = 6. f(-1) = 0. f(0) = 1
