If f(x) = x2 and g(x) = 3x + 1, then g(f(2))= ?
andreyandreev [35.5K]

Answer:

The value of g[f(2)] = 13

Step-by-step explanation:

Given functions:

f(x) = x²

g(x) = 3x + 1

Find:

The value of g[f(2)]

Computation:

f(x) = x²

By putting x = 2 in f(x)

f(x) = x²

f(2) = 2²

f(2) = 2 × 2

f(2) = 4

So the value of f(2) = 4

Value of  f(2) putting in g(x)

g(x) = 3x + 1

g(x) = 3x + 1

g[f(2)] = 3[f(2)] + 1

We know that f(2) = 4

So,

g[f(2)] = 3[f(2)] + 1

g[f(2)] = 3[4] + 1

g[f(2)] = 12 + 1

g[f(2)] = 13

The value of g[f(2)] = 13

50 + 35m

Steps:
100 + 35m = 50 + 35m <span>

<em>Set the equations equal to each other.</em>
</span>   <span />
<span>
100 + 35m = 50 + 35m <span>
-50              - 50
</span>
<em>Subtract 50 from both sides of equation to isolate the variable on one side</em>.

50+35m=35m
     -35m  -35m

<em>Subtract 35m from both sides of equation.</em>

50=m

In fifty months, they will have the same amount of money. They will each contain $1850 dollars.

Hope this helps.
