{ (2, √2), (3,√3 ), (4, 2) ,(5, √5 ), (6, √6), (7, √7), … }
a. (8,8) b. ( √8, 8) c. (8, 2√2) d. (8, -8)
2. Which of the following has a graph of a function?
a. x2 + y2 = 9 b. x2 - y2 = 1 c. y - x2 = 4 d. x - y2 = 16
3. Which of the following correspondence is a function?

a. i only b. ii only c. ii and iii d. i and iii
4. What value of x will make { (3,5) ,(7,9), (x – 3, 13) , (15, 17)} satisfy the relation y = x + 2?
a. 6 b. 10 c. 14 d. 18
5. Which of the following is not a function?
a. The rule which assigns to each integer its factor
b. The rule which assigns to every person his/her biological father

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

12

step-by-step explanation:

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
