Select the correct answer. This table models function m.
Function n represents a cubic function that passes through the points (-1,0) and (0,2).
Which statement is true?
A.
The y-intercept of m is less than the y-intercept of n.
B.
The y-intercept of m is not given.
C.
The y-intercept of m is equal to the y-intercept of n.
D.
The y-intercept of m is greater than the y-intercept of n.

A.

The y-intercept of m is less than the y-intercept of n.

Step-by-step explanation:

y-intercept of a function:

The y-intercept of a function is the value of y when

Function n represents a cubic function that passes through the points (-1,0) and (0,2).

When , and thus, the y-intercept is y = 2.

Function m:

When , and thus, the y-intercept is y = -6, which is a smaller number than 2, so the y-intercept of m is less than the y-intercept of n, and the correct answer is given by option A.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
