4x^2+13=49

To solve the value of x in the above equation, here are the steps.

1. Subtract 13 on both sides of the equation.

\begin{gathered} 4x^2+13-13=49-13 \\ 4x^2=36 \end{gathered}

2. Divide both sides of the equation by 4.

\begin{gathered} \frac{4x^2}{4}=\frac{36}{4} \\ x^2=9 \end{gathered}

3. Get the square root on both sides of the equation.

\begin{gathered} \sqrt[]{x^2}=\sqrt[]{9} \\ x=\pm3 \end{gathered}

The possible values of x are +3 and -3. The smaller value is -3.

Three functions are given below: f(x), g(x), and h(x).
Rzqust [24]

Answer: The axis of symmetry is x=1.

Explanation:

The given function is,

g(x)=5x^2-10x+7

The degree of the equation is 2.  SInce it is a quadratic function therefore the graph of the function is a parabola.

The axis of symmetry of a parabolic function f(x)=ax^2+bx+c is a vertical line,

x=-\frac{b}{2a}

Since the value of a is 5m b is -10 and c is 7, So the axis of symmetry is,

x=-\frac{(-10)}{2(5)}

x=\frac{10}{10}

x=1

Therefore, the axis of symmetry is x=1.
