First what we are going to want to do is set h(x) as 0.
0=1/4(x+4)2-3
Now, start with the equation solving process.
Add 3 to both sides.
3=1/4(x+4)2
Multiply by 4 on both sides.
12=(x+4)2
Square root on both sides
\(\sqrt{12}=x+4\)
Subtract 4.
sqrt(12)-4 = -0.5358983848622454
So x=-0.5358983848622454
