Find a possible equation for the functions below a Use the g

Find a possible equation for the functions below.

a) Use the general exponential formula

points (-2,0.48) and (2,18.75)

b)The vertical asymptote is x=-3 and the horizontal asymptote is y=1

a) general exponential equation is y=ab^x , contains (-2,0.48) and (2,18.75)

0.48 =ab^-2

18.75 =ab²

18.75*0.48 =ab²ab^-2

18.75*0.48 =a²

a=3

y=3b^x contains (-2,0.48)

0.48 =3b^-2

0.16 =b^-2

b=2.5

equation is y=3(2.5)^x

b)vertical asymptote is x=-3 => denominator conatins x+3

horizontal asymptote is y=1

numerator canbe any first degree polynomial with coefficient 1 except x+3

for example y =(x+4)/(x+3)
