The piecewise function f(x) has opposite expressions. (2x - 1, x <0
f(x) = 0,
1-2x + 1, x > 0
Which is the graph of f(x)?
22
3 4 5
4-) -2 -110
45

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
