The graph lies in 2nd and 3rd consider x?y? = -1 ⇒ x = - 1/?y?. This is the only option which admits x negative. |
Directions: Read the following information to answer the question.
The graph is y = f(x) = - ?x? + 2
Clearly f(x) = f(x)
Directions: Read the following information to answer the question.
Basically, the equation describes 10 squares of sides ?2, 2?2, 3?2, ….., 10?2. Sum of the areas of the squares is 2(12 + 22 + 32 + ….102)
= 2 x 385 = 770 sq. units
