Answer: The range of the function is all real numbers is true.

Explanation: the graph of y = 1/3 is just a horizontal line at y = 1/3. so it’s not increasing or decreasing (it’s staying the same). there is no x-intercept, and the y-intercept is (0, 1/3). the range is all the possible y values, and there are infinite possible y values, so it is all real numbers.

hope this helps!

On the day Alexander was born, his father invested $5000in an account with a 1.2% annual growth rate. Write a function, A(t) tha

stepladder [879]

Answer:

Equation: $A(t)=5000(1.012)^n$

Worth more in 32 yr than in 17 yr by: $1199.92

Step-by-step explanation:

THe compound growth formula is:

$F=P(1+r)^n$

Where

F is the future amount (here, A(t))

P is the initial amount, here 5000

r is the rate of growth in decimal, 1.2% = 1.2/100 = 0.012

n is the time in years

Thus, we can say the function would be:

$A(t)=5000(1+0.012)^n\\A(t)=5000(1.012)^n$

Now, we want how much more it will be worth when 17 years and 32 years. We find the future amount, A(t), when n= 17 and n = 32 and find the difference. Shown below:

$A(t)=5000(1.012)^n\\A(17)=5000(1.012)^{17}\\=6124.05$
