Given the square root function, y=12x+3−−−−√−9, what is the y-value when x=13?(1 point) Responses
2
−1
−5
−7
To find the y-value when x=13 in the given function, you substitute x=13 into the function and simplify:
y = 12(13) + 3 - √(-9)
y = 156 + 3 - √(-9)
y = 159 - √(-9)
Since the square root of a negative number is undefined in real numbers, the y-value is undefined when x=13. Hence, there is no valid answer among the given options.
