y = (4)/(9x – 45)

What do you want?
Where it is undefined is where 9x = 45 or x = 5
is there a question in there somewhere?
Sorry, my oversight...
what is the excluded value of the function?
y = 4/(9x – 45)
• –5
• 0.2
• 5
• –0.2
To find the value of y when x = -5 in the equation y = 4/(9x - 45), substitute -5 in place of x and solve for y.
Step 1: Start with the equation y = 4/(9x - 45).
Step 2: Replace x with -5 in the equation: y = 4/(9(-5) - 45).
Step 3: Simplify the expression inside the parentheses: y = 4/(-45 - 45).
Step 4: Continue simplifying: y = 4/(-90).
Step 5: Divide 4 by -90: y = -0.0444 (rounded to four decimal places).
Therefore, when x = -5, y ≈ -0.0444. So, the answer is -0.2 (closest option).
