No,
although all the sides are the same length on an equilateral triangle the height is calculated by a straight perpendicular line at the mid point of the base.
The sides are not perpendicular with the base and are angled outwards

You can determine this by finding zeros of quadratic function,
.
Which eliminates first and third option.
Now we have up and down parabolas left.
If we factor we find that the coefficient before
determines how it is turned, since its positive its an upward turned parabola hence the answer is the last graph.
Hope this helps.
