Given the relation y = 3x2 + 1, if the input is 4, what is the output? (4 points)
13
48
49
145

Option C is correct.

The output is 49.

Explanation:

Given the relation:                   ....[1]

A function is a relation in that each input has only one output.

In the given relation,  y is a function of x

for input x=4 ,

Substitute the value of x =4 in equation [1];

or

therefore, for the given input the output is 49.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
