@sooobored

OpenStudy (sooobored):

initial value of 1 means g(0)=1 which also means the y-intercept for g(x) is 1

OpenStudy (sooobored):

what is the y intercept of f(x)?

OpenStudy (jamaljunior):

.1?

OpenStudy (sooobored):

oh crap, i got that backwards g(x) is the linear function and f(x) is the exponential function everything i said above needs to be reversed the y-intercept of f(x) is 1 so you need to find the y intercept of the linear function g(x)

OpenStudy (sooobored):

and no it is not .1 linear function what is the slope?

OpenStudy (sooobored):

at x=2 y=11 at x=3 y=14 just by simply looking at these 2 points, we can conclude the slope is 3 so at x=1 y=8 therefore at x=0 y=?

OpenStudy (jamaljunior):

idk @sooobored

OpenStudy (danjs):

f(x)=A*b^x g(x)=mx+b

OpenStudy (danjs):

\[\large f(x)=3^x\] \[\large g(x)=3x+5\]

OpenStudy (danjs):

The y-intercept occurs when x=0, so for each function the y intercept value is f(0)=3^0=1 g(0)=3*0+5=5 the difference between those two values is 5-1=4
