STEP 1:Find the x-intercepts
To find the x-intercepts solve, the equation $ \color{blue}{ 4x+5 = 0 } $
The solution of this equation is:
$$ \begin{matrix}x = -\dfrac{ 5 }{ 4 } \end{matrix} $$(you can use the step-by-step polynomial equation solver to see a detailed explanation of how to solve the equation)
STEP 2:Find the y-intercepts
To find the y-intercepts, substitute $ x = 0 $ into $ \color{blue}{ p(x) = 4x+5 } $, so:
$$ \text{Y inercept} = p(0) = 5 $$STEP 3:Find the end behavior
The end behavior of a polynomial is the same as the end behavior of a leading term.
$$ \lim_{x \to -\infty} \left( 4x+5 \right) = \lim_{x \to -\infty} 4x = \color{blue}{ -\infty } $$The graph starts in the lower-left corner.
$$ \lim_{x \to \infty} \left( 4x+5 \right) = \lim_{x \to \infty} 4x = \color{blue}{ \infty } $$The graph ends in the upper-right corner.
