The first 3 figures in a pattern are shown. PART 1:Which of the following functions represents f(n), the number of small squares in figure n?

A) f(n) = 2n^2

B) f(n) = (n + 4) ^2

C) f(n) = 5n + 4

D) f(n) =n^2 + 4

PART 2:How many small squares will be in the 15th figure?

A) 60

B) 79

C) 229

D) 361

hehe is it d

Step-by-step explanation:

hehe

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

is this part of a question or something
