Answer: -5/14

Step-by-Step Explanation:

= -9/14 + 2/7 (Take LCM of Denominator)
= -9/14 + (2 * 2)/14 (Taking 14 as LCM)
= -9/14 + 4/14 (Add the Numerators)
= (-9 + 4)/14
=> -5/14

Use the function below to find f(4).<br> f(x)= 1/3•4^x
kenny6666 [7]

Answer:

f(4) = 85 1/3 or 85.333...

Step-by-step explanation:

To find f(4), you must substitute 4 in place of x whenever x appears:

f(x) = \frac{1}{3} * 4^{x}

f(4) = \frac{1}{3} * 4^{4}

Next, simplify the exponent:

f(4) = \frac{1}{3} * 256

Finally, multiply:

f(4) = 85 1/3 or 85.333...
