Evaluate the function as indicated. Determine its domain and range?

Question

F(x) = (2x+1, x<0)

(2x+2, x>,=0) (greater than or equal to 0)

a)f(-1)

b)f(0)

c)f(2)

d)f(t^2+1)

Answer 1

X

Answer 2

1

Answer 3

a)  f(-1)  =  2(-1) + 1 = -1

b)  f(0)   =  2(0) + 2=  2

c)  f(2)  =  2(2) + 2 = 6



d)  since t^2 + 1 is always positive so v&#039;ll take the second function

f(t^2 + 1)  =  2(t^2 + 1) + 2  =  2*t^2   +  4
