For one of my subjects which had an exam hurdle of 50% i got 68% overall but don't know what i got in the exam, and don't know my assignment grades either. If I got over 50% overall but failed the exam hurdle would my grade show up differently?

Hi, can I please have some help with the below questions? f(x) =sqrt(x+1), with a restricted domain of [0, infinity), h(x) = x^2+3, with a domain of R, to find the range of the composite function f(h(x)), the domain would be the domain of the inner function, h(x), which is R, but do we also need...
