Answer: g(x)=3x^2+8

Step-by-step explanation:

There are some transformations for a function f(x). Two of those transformations are:

1. If f(x)+k, then the function is translated "k" units up.

2. If f(x)-k, then the function is translated "k" units down.

In this case, you have the following Quadratic function  f(x) given in the exercise:

f(x)=3x^2+5

According to the information given, the function g(x) is obtained by translating the  Quadratic function  f(x)  3 units up. Based on this, you can identify that the transformation is the following:

 f(x)+k

Where k=3

Therefore, you can determine that:

g(x)=f(x)+3=3x^2+5+3\\\\g(x)=3x^2+8

3<br>Find the value of a <br>in the equation,(3+4√3)(2-a√3)=-18+2√3​
ankoles [38]

Given:

The equation is:

\left(3+4\sqrt{3}\right)\left(2-a\sqrt{3}\right)=-18+2\sqrt{3}

To find:

The value of a.

Solution:

We have,

\left(3+4\sqrt{3}\right)\left(2-a\sqrt{3}\right)=-18+2\sqrt{3}

On simplification, we get

(3)(2)+(4\sqrt{3})(2)+(3)(-a\sqrt{3})+(4\sqrt{3})(-a\sqrt{3})=-18+2\sqrt{3}

6+8\sqrt{3}-3a\sqrt{3}-4a(3)=-18+2\sqrt{3}

6+8\sqrt{3}-3a\sqrt{3}-12a=-18+2\sqrt{3}

(6-12a)+(8-3a)\sqrt{3}=-18+2\sqrt{3}

On comparing both sides, we get

6-12a=-18

-12a=-18-6

a=\dfrac{-24}{-12}

a=2

And,

8-3a=2

-3a=2-8

a=\dfrac{-6}{-3}

a=2

Therefore, the value of a is 2.
