The domain is which gives
The function will be defined only if (since square root of a negative term is not possible)
can someone please explain to me how to do this.
Find the value of a which will ensure that the domain of the function
f(x) = −9
√(a x+10) (-9 over sqrt(ax+10))
is the interval (−∞, 3), i.e. x < 3.
do you need to find the value of a, when x is 3? I'm a bit confused :S
