What is the equation of an exponential function with base=2 that has a vertical stretch by a factor of 3, a shift to the right 5

il63 [147K]

Answer:

$y=3(2)^{x-5}+6$

Step-by-step explanation:

Let the equation of the exponential function with base 2 is,

$y=a(2)^{x+c}+d$

Here, a = vertical stretch

c = Horizontal shift

d = Vertical shift

If this function has a vertical stretch by a factor of 3,

Equation will be,

$y=3(2)^{x+c}+d$

If this function has a shift of 5 to the right,

Equation of the function will be,

$y=3(2)^{x-5}+d$

If this function has a shift of 6 units upwards,

$y=3(2)^{x-5}+6$

Biff is 25 years older than Hannah today. Four years from now,Biff will be 6 times as old as Hannah will be. How old is Hannah t

gavmur [86]

Hannah is 1 year old today.

Step-by-step explanation:

Let,

Hannah = x

Biff = y

According to given statement;

y = x+25 Eqn 1

In four years;

y+4 = 6(x+4) Eqn 2

Putting value of y from Eqn 1 in Eqn 2;

$(x+25)+4=6x+24\\x+25+4=6x+24\\x+29=6x+24\\29-24=6x-x\\5=5x\\5x=5$

Dividing both sides by 5

$\frac{5x}{5}=\frac{5}{5}\\x=1$

As x is age of Hannah, therefore,

Hannah is 1 year old today.
