which is the graph of f(x) = 2(3)+x

Step-by-step explanation:

Hello, Sam,

Weren't there graphs to share?

f(x) = 2(3)^x is an increasing exponential.  It begins in Quadrant II and continues to grow in Quadrant I.

The y-intercept is found by setting x = 0:  f(0) = 2(3)^0 = 2, and as a point it is (0, 2).  Plot this point.  Starting in the far left of Quadrant II, draw a curve with a very gentle slope to and through (0, 2).  Once you're past x = 0, give the graph a steadily increasing slope, in Quadrant I.

for A)

if she has $ for the downpayment of $70

for B)

360-70+290

290/ 5=58

amount paid = 290-58(#month)

a=290-58m

ANSWER

A= -58m+290
