I actually don’t get this and I have a test in 2 days please help what is g(x) and how

Answers

first off, is noteworthy that's the graph of an exponential function, thus the function will be along the lines of g(x) = abˣ , now, what's "a" and "b" values?

well, let's take a peek when x = 0 and x = 1.

$\bf g(x) = ab^x \n\n[-0.35em] ~\dotfill\n\n \begin{cases} x = 0\n y = 1 \end{cases}\implies 1=ab^0\implies 1=a(1)\implies \boxed{1=a} \n\n[-0.35em] ~\dotfill\n\n \begin{cases} x = 1\n y = 4 \end{cases}\implies 4 = ab^1\implies 4=1b^1\implies \boxed{4=b} \n\n[-0.35em] ~\dotfill\n\n ~\hfill g(x) = 4^x\qquad \qquad \qquad \begin{array}{|c|c|ll} \cline{1-2} x&y\n \cline{1-2} -2&(1)/(4^2)\to (1)/(16)\n -1&(1)/(4)\n 0&1\n 1&4\n 2&16\n \cline{1-2} \end{array}~\hfill$
