5) The grass in the backyard of a house is a square with side length 10m. A square patio is placed in the centre. If the side length, in meters, of the patio is x, then the area of
the grass remaining is given by the relation A=-x? +100.
a) Graph the relation.
Colon
I
b) Find the intercepts. What do they represent?
c) How do the equation change if the grass in the backyard of a house is a square with
side length 12 m.
d) For what values of x is each equation valid?

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

x=0
