HELP!!!! 3. Find the x-intercept of the graph of the linear equation y = 2x + 4.

Hi there!

I believe your answer is:

(-2, 0)

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

$\text{Substitute in \textbf{0} for } y \text{ and solve for } x\text{.}\\-------------------\\y = 2x+4\\-------------------\\\rightarrow 0 = 2x +4\\\\\rightarrow 2x + 4 = 0\\\\\rightarrow 2x +4 - 4 = 0 - 4\\\\\rightarrow 2x = -4\\\\\rightarrow\frac{2x=-4}{2}\\\\\rightarrow \boxed{x=-2}$

⸻⸻⸻⸻

$\text{The \textbf{x-intercept} of the given equation is: } (-2, 0)$

1.
g(x) = 3 - x^2
g(-2) = 3 - (-2)^2 = 3 - 4 = -1

f(x) = 5x + 4
g(g(-2)) = f(-1) = 5(-1) + 4 = -1

2.
f(x) = 5x + 4
f(-2) = 5(-2) + 4 = -10 + 4 = -6

g(x) = 3 - x^2
g(f(-2)) = g(-6) = 3 - (-6)^2 = 3 - 36 = -33
