If you vertically stretch the exponential function f(x)=2^x by a factor of 3, what is the equation of the new function

AleksAgata [21]

Answer:

$y=3*2^{x}$

Step-by-step explanation:

A vertical stretch of a function means the output values have changed by a factor of 3 or multiplication by 3. Recall, an exponential function has the basic form

$y=ab^{2}$ .

If our equation is $f(x)=2^x$ , then a=1. To stretch it vertically by a factor of 3, we multiply a by 3. So 1(3)=3. The value of a now becomes 3.

$y=3*2^{x}$

Hunter owns a food truck that sells tacos and burritos. He sells each taco for $3.25

WITCHER [35]

Answer:

y = 40 x = 80

Step-by-step explanation:

520 = 3.25x + 6.5y x+y=120

x+y=120

x = 120-y

520 = 3.25(120-y)+6.5y

520 = 390-3.25y+6.5y

520 = 390+3.25y

130=3.25y

Divide each side by 3.25

40 = y

x = 120-y

x = 120-(40)

x = 80
