intro

Equations are used to represent the relationships between variables. In , the variables are x & y and the following observations are true for the given equation:

Given that:

the square of x

So, means that: the y is 1 less than the square of x

From the attached table, we have:

This means that:

Also, we have:

This means that:

Collect like terms

Take square roots

Hence, the values of a and b are 3 and 0, respectively.

The graph options are not made available. So, I will plot the graph of .

ian gone lie this got me confused

step-by-step explanation:

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
