Question

Help pretty please and explain

Answer 1

Any function in the form $f(x)=a*(b)^x$ is known as an exponential function. And one of the important things to know about such functions is that the $a$ is the value of the function when $x=0$. Check it out:

$f(0)=5*(6)^0$

Recall that any number to the zero power is 1, so this becomes:

$f(0)=5*1 \newline \newline f(0)= 5$

So, again, when $x=0$ we see that $y=5$. (Don't forget that $y$ is the same thing as $f(x)$!) This represents the point $(0,5)$, which is also the y-intercept of the function!
