What is the axis of symmetry for f(x) = −5x2 − 20x − 10
Tasya [4]
<span>For this case we have the following function:
</span> f(x) = -5x^2 - 20x - 10&#10;
<span> To find the axis of symmetry, the first thing to do is to derive the function.
 We have then:
</span> f '(x) = -10x - 20 &#10;
<span> Equaling zero we have:
</span> -10x - 20 = 0 &#10;
<span> We clear the value of x.
 We have then:
</span> -10x = 20 &#10;&#10;x = -20/10 &#10;&#10;x = -2 &#10;
<span> Answer:
 The axis of symmetry is given by:
 x = -2</span>
