Question

plotting the x - intercept
plot the x - intercept of the function ( f(x) = (x + 4)^2 ).
where is the x - intercept located?
options: ((4,0)), ((0, - 4)), ((-4,0)), ((0,4))
click or tap the graph to plot a point.

Explanation:

Step1: Set $f(x)=0$

$0=(x+4)^2$

Step2: Solve for $x$

Take square root: $\sqrt{0}=\sqrt{(x+4)^2}$
Simplify: $0=x+4$
Rearrange: $x=-4$

Step3: Identify x-intercept

x-intercept is $(-4,0)$

Answer:

$(-4, 0)$
