The right answer is: f[g(4)] = 45

Step-by-step explanation:

First of all, we have to find g(4)

So,

g(4) = 3(4)-7\\= 12-7\\=5

Now to find f(g(4)) we will put the value of function g on 4 in place of x in function f

f(g(x)) = 2(g(4))^2-5\\= 2(5)^2 -5\\= 2(25) -5\\= 50-5\\=45

Hence,

The right answer is: f[g(4)] = 45

Answer:

Option (3)

Step-by-step explanation:

Properties for the vertical stretch or shrink of a function,

If a function is f(x) = k|x|

1). Function will be vertically stretched if k > 1

2). Function will have a vertical shrink if 0 < k < 1

To fit the given data graph of f(x) = |x| will vertically shrink without any translation along x or y-axis.

And the value of k will be, 0 < k < 1.

Therefore, g(x) = \frac{1}{3}f(x) will be the transformed graph.

Therefore, Option (3) will be the correct option.

luda_lava [24]

Answer: C

Step-by-step explanation:

This describes an expotential function

At t = 0, P = 70

Therefore, C = 70

P = 70 e^kt

Solve for k by plugging in (4,360)

k = 0.4094

plug in t(7 hours)

70 e^(0.4094*7)

The answer roughly equals C
