Explain how you can determine that the following system has one unique solution – without actually solving the system.

For f(x)=2x+3 and g(x)=x^2- 8 find (f+g) (x)

F(x) = 1/x g(x)=x-4 can you evaluate (g*f)(0) ? why or why not?

Match each whole number with a rational, exponential expression 3 square root 27^2find the domain and range of the exponential function h(x)=125^x. explain your findings. as x decreases does h increase or decrease? explain. as x increases does h increase or decrease? explain.
