<span>x intercept when f(x) = 0
so
</span><span>x^2-81 = 0
x^2 = 81
x = + 9 and x = -9
Answer
</span><span>C -9</span>
Subtract 4<span> from both sides
</span><span><span>y−4>−2x</span>
<span>Divide both sides by -2
</span>
x>-y-4/2
Question 2 - y>x-4
Add 4 to both sides
<span><span>y+4>x
Switch sides
</span>
<span><span>x<y+4</span><span>
</span></span></span>
