Nth term of 7 9 11 13 15

1 answer:

8 0

The secret formula seems to be: 7 plus 2 plus 2 plus 2...

so 7+2....

but the plus 2 is repeated!

so

7+(2*x)

how many times is it repeated? 7 is the first term, 9 is the second, but it's repeated only once.. so the number of the term -1!

like this:

7+(2*(n-1))

The equation in the vertex form of g(x) is:

$g(x) = (x + 1)^2 - 38$

<h3>How to get the equation of function g?</h3>

We know that g(x) is a translation of 2 units below and 3 units to the left of f(x).

So first, let's rewrite f(x) to its vertex form:

$f(x) = x^2 - 4x - 32$

The vertex is at:

$x = -(-4)/2*1 = 2$

The y-value of the vertex is:

$f(2) = 2^2 - 4*2 - 32 = -36$

Then the vertex form of f(x) is:

$f(x) = (x - 2)^2 - 36$

If we move this vertex 2 units below, and 3 units to the left, then we have:

$g(x) = f(x +3) - 2\\\\g(x) = (x - 2 + 3)^2 - 36 - 2\\\\g(x) = (x + 1)^2 - 38$

That is the equation for g(x) in vertex form.

What is the complex conjugate of -8+12i

Nuetrik [128]

The complex conjugate of a + bi is a - bi

So, the complex conjugate of -8 + 12i is -8 - 12i.
