The graph of y = square root of 9 - x end square root - 5 is shown below. What are the x-intercept and the y-intercept, and for
what values of x is the function defined?
answers:
x-Intercept: (−16, 0), y-intercept: (0, −2), x ≥ 9
x-Intercept: (−16, 0), y-intercept: (0, −2), x ≤ 9
x-Intercept: (−16, 0), y-intercept: (0, −2), x ≥ −5
x-Intercept: (0, −2), y-intercept: (−16, 0), x ≥ −2
answers:
x-Intercept: (−16, 0), y-intercept: (0, −2), x ≥ 9
x-Intercept: (−16, 0), y-intercept: (0, −2), x ≤ 9
x-Intercept: (−16, 0), y-intercept: (0, −2), x ≥ −5
x-Intercept: (0, −2), y-intercept: (−16, 0), x ≥ −2

Answer: 4.5
<u>Step-by-step explanation:</u>
First, find the points of intersection by solving the system.
y = x² + 2x + 4
y = x + 6
Solve by substitution:
x² + 2x + 4 = x + 6 ⇒ x² + x - 2 = 0 ⇒ (x + 2)(x - 1) = 0 ⇒ x = -2, x = 1
Now, integrate from x = -2 to x = 1
<em>the bottom of the integral is -2 </em>
