C. The x-intercepts cannot be compared because either por q does not have an x-intercept.

D. The x-intercept of function p is the same as the x-intercept of function q.

The x-intercept of p(x) is x = 2, the x-intercept of g(x) is x = 0, then the correct option is B.

<h3>What can we say about the x-intercepts of the given functions?</h3>

For a function f(x), the x-intercept is the value of x such that:

f(x) = 0.

Here we have:

p(x) = log₂(x - 1)

Remember that:

logₙ(1) = 0

For any base n, then the x-intercept of p(x) is x = 2, because:

p(2) = log₂(2 - 1) = log₂(1) = 0.

The other function is:

g(x) = 2ˣ - 1

Remember that any number to the power of zero is equal to 1, then:

g(0) = 2⁰ - 1 = 1 - 1 = 0

The x-intercept of p(x) is x = 2, the x-intercept of g(x) is x = 0, then the correct option is B.

How do you determine if a triangle is isosceles, scalene, or equilateral?

Answer:

A triangle is scalene if all of its three sides are different. If two of its sides are equal, a triangle is called isosceles. A triangle with all three equal sides is called equilateral.

Find the recursive quadratic formula of the sequence: 1, 3, 7, 13, 21

Anika [276]

The sequence

1, 3, 7, 13, 21, ...

has first-order differences

2, 4, 6, 8, ...

Let $a_n$ denote the original sequence, and $b_n$ the sequence of first-order differences. It's quite clear that

$b_n=2n$

for $n\ge1$ . By definition of first-order differences, we have

$b_n=a_{n+1}-a_n$

for $n\ge1$ , or

$a_{n+1}=a_n+2n$

By substitution, we have

$a_n=a_{n-1}+2(n-1)$

$\implies a_{n+1}=(a_{n-1}+2(n-1))+2n$

$\implies a_{n+1}=a_{n-1}+2(n+(n-1))$

$a_{n-1}=a_{n-2}+2(n-2)$

$\implies a_{n+1}=(a_{n-2}+2(n-2))+2(n+(n-1))$

$\implies a_{n+1}=a_{n-2}+2(n+(n-1)+(n-2))$

and so on, down to

$a_{n+1}=a_1+2(n+(n-1)+\cdots+2+1)$

You should know that

$1+2+\cdots+(n-1)+n=\dfrac{n(n+1)}2$

and we're given $a_1=1$ , so

$a_{n+1}=1+n(n+1)=n^2+n+1$

or

$a_n=(n-1)^2+(n-1)+1\implies\boxed{a_n=n^2-n+1}$

Alternatively, since we already know the sequence is supposed to be quadratic, we can look for coefficients $a,b,c$ such that

$a_n=an^2+bn+c$

We have

$a_1=a+b+c=1$

$a_2=4a+2b+c=3$

$a_3=9a+3b+c=7$

and we can solve this system for the 3 unknowns to find $a=1,b=-1,c=1$ .
