to which family does the function y = 2^x+5 belong?\nquadratic\nsquare root\nexponential\nlogarithmic

Brief Explanations:

The general form of an exponential function is $y = a^x + b$ (where $a>0,a\neq1$). In the given function $y = 2^x+5$, the variable $x$ is in the exponent. A quadratic function has the form $y=ax^{2}+bx + c$, a square - root function has the form $y=\sqrt{x}$ or similar, and a logarithmic function has the form $y=\log_a x$.

Answer:

C. exponential
