Question

Find f(-2) for f(x) = 5•3*x

Answer 1

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!

Answer 2

The value of f(-2) is 0.56

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* (1)/(3^2)`

`f(-2)=(5)/(9)=0.5555...\sim 0.56`

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