A giant bamboo plant grew an average of 18 centimeters per year.The botanist started measuring the plant when it was 5 centimete
Anastaziya [24]
H=height
y=number of years.

we have the next expresion:
h(y)=my+b  

m=the slope of the line, in this case, the slope is equal to "18"; (18 cm/ year).
b=the initial heigth, in this case, the initial heigth is equal to "5" (5 cm).

Therefore, our  expression will be:
h(y)=18y +5

answer: h(y)=18y+5

Which is f(-3) for the quadratic function graphed
hodyreva [135]
         We have to find on the graph which is f ( - 3 ).
         This is the quadratic function which passes through the points: ( - 6, - 3 ), ( 0 , - 3 ) and ( - 3, - 9 ).
         Also we can conclude that the point ( - 3, - 9 ) is the minimum value of this function. So : f ( - 3 ) = - 9.
        Answer:
        A ) - 9.
