Find f(-2) for f(x) = 5•3*x

Mathematics
2 answers:
Oksanka [162]3 years ago
8 0

Answer:

The value of f(-2) is 0.56

Step-by-step explanation:

Given the function

f(x)=5.3^x

we have to find the value of f(-2)

f(x)=5.3^x

Put x=-2

f(-2)=5.3^{-2}

f(-2)=5\times \frac{1}{3^2}

f(-2)=\frac{5}{9}=0.5555...\sim 0.56

Hence, the value of f(-2) is 0.56

Hello!

You put -2 in for x

I don't know whether it is times x or to the power of x so I will do both

5 * 3 * x

5 * 3 * -2 = -30
------------------------------------------------------------------------------------------------------
5 * 3^x

5 * 3^-2

5 * 1/81 = 5/9 or 0.55555

Hope this helps!
