The graph below shows four straight lines, w, x, y, and z.

which line is represented by the function f(x) = 3x + 5?
a: line w
b: line x
c: line y
d: line z

Option B. Line X

Step-by-step explanation:

The graph shows four straight lines W, X, Y, Z.

We have to identify the line which represents the function f(x) = 3x + 5

The given equation is y = 3x + 5, in which slope of the line should be 3 and y- intercept is 5.

In these lines line x is having y-intercept as 5.

Line x passes through (-1, 2) and (0, 5)

So slope of the given line will be =

=

= 3

Therefore, option B : Line X is the answer.

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.

i believe it's a.

i'm not sure on this one, most likely correct.
