I need help with this question in math

The graph of h(x)= |x-10| +6 is shown. on which interval is this graph increasing

It is given that the quadratic equation hx²-3x+k=0, where h and k are constants, has roots [tex] \beta \: and \: 2 \beta [/tex]express h in terms of k

The tiles on the left contain functions written using function notation . match each function with its input
