Answer:
<h2>-4</h2>
Step-by-step explanation:
Given the function f(x)=(x+4)², <u>the x intercept occurs at f(x) = 0,</u> substituting f(x) = 0 into the given equation to get the value of x we have;

Taking the square root of both sides

Subtracting 4 from both sides of the equation

Therefore the x intercept of the equation is -4

an = -3n + 15 + 3
an = -3n + 18
