G(x) will be g(x)=-2x-3 because it is a reflection of f(x) over the x-axis. F(x)'s reflection over the x-axis will become -f(x).

Answer:

g(x)=-x^2-3

Step-by-step explanation:

The parent function is x^2+3

Now, the function g(x) is obtained by reflecting the graph of f(x) about the x-axis.

When the parent function f(x) is reflected about the x-axis then the translated function is -f(x)

Therefore, we have g(x)=-f(x)

Hence, the equation of g(x) is

g(x)=-f(x)\\\\g(x)=-(x^2+3)\\\\g(x)=-x^2-3

Quick I need an answer to this Queston:
fiasKO [112]

Step-by-step explanation:

-  \frac{3}{4} x + 2 \frac{1}{4 } =  \frac{1}{2} x + 1

-  \frac{3}{4} x +  \frac{9}{4}  =  \frac{1}{2} x +  \frac{2}{2}

\frac{ - 3x + 9}{4}  =  \frac{2x + 4}{4}

- 3x + 9 = 2x + 4

- 3x - 2x = 4 - 9

- 5x =  - 5

x =  \frac{ - 5}{ - 5}

x = 1

The answer is C.
