f(x) = 4*3^x calculate f(10) and f(1)

We store the definition:

f (x) = 4 \cdot 3^{x}

Applying the definitions,

f (10)

becomes

4 \times 3^{10}

Let's evaluate:

4 \times 3^{10}

ⓘ Powers are computed before multiplications, additions and subtractions. A power with a positive integer exponent is a repeated product:

3^{10}

3 \times ... \times 3

, 10 times =

59,049

4 \times 59,049

▶Result:

236,196

Applying the definitions,

f (1)

becomes

4 \times 3^{1}

Let's evaluate:

4 \times 3^{1}

▶Result:

12
