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

Expression 20 – 3J represents the change in dollars, which construction worker will receive after buying J bottles of juice.
<u>Solution:</u>
Given that
A construction worker bought several bottles of juice for $3 at the comedian store
She paid for them the $20 bills
Number of bottles of juice is represented by variable J
Need to write an expression for the change she receives.
From given information
Price of 1 juice bottle = $3
<em>Change she receives = Amount she paid - price of J juice bottles </em>
=> Change she receives = 20 – 3J
Hence expression 20 – 3J represents the change in dollars, which construction worker will receive after buying J bottles of juice.
