Mark all that apply

•  $-\infty<x<1.5\ \$  

•  $1.5<x<3.9\ \$  
  

•  $3.9<x<\infty$  
  

•  $\ 3.9\le x<\infty\ \$  

•  $-\infty<x\le1.5\ \$  

Which of the following is the correct method of describing the decreasing y values of the function through its x values?

Mark all that apply

•  $-\infty<x<1.5\ \$  

•  $1.5<x<3.9\ \$
