Question

Which function increases faster

Answer 1

it is asking what has higher slope

slope=rise/run=changey/changex

for (x1,y1) and (x2,y2), slope is (y2-y1)/(x2-x1)

for the h(t) one

consider (0,-6.5) and (1,-5.75)

slope is (-5.75-(-6.5))/(1-0)=(-5.75+6.5)/1=0.75/1=0.75

for the graph one

points (0,-6) and (8,0)

slope=(0-(-6))/(8-0)=(0+6)/8=6/8=3/4=0.75

they increase at the same rate
