The graph shows how much a plant grew after it was purchased. Which statement is not correct?
Luda [366]

Answer:

The plant grows 1 cm every day is the incorrect statement

Step-by-step explanation:

The graph shows that for every 10 days the plant grows 1 cm

10/2 = 5

so in 5 days the plant would grow half of what it does in 10 days so 1/2 or 0.5 cm

10/10 = 1

so in 1 day the plant would grow a tenth of what it does in 10 days so 1/10 or 0.1 cm

G(x)=-f(x)-2
x=-2→g(-2)=-f(-2)-2=-(-1)-2=1-2→g(-2)=-1
x=-1→g(-1)=-f(-1)-2=-(1)-2=-1-2→g(-1)=-3
x=0→g(0)=-f(0)-2=-(3)-2=-3-2→g(0)=-5
x=1→g(1)=-f(1)-2=-(5)-2=-5-2→g(1)=-7
