Answer:

It depends on what you meant. See below.

Step-by-step explanation:

What you wrote means this:

f(x) = \dfrac{4}{9}x + 7

This is linear.

If you meant this

f(x) = \dfrac{4}{9x} + 7

or this

f(x) = \dfrac{4}{9x + 7}

then it's non-linear.

An x in the denominator makes a function non-linear.

Find the range of f(x) = -x2 + 1 for the domain {-2, 0, 2}
wariber [46]
Range is just input the domain

so find f(-2), f(0) and f(2)

f(-2)=-(-2)²+1=-4+1=-3
f(0)=-(0)²+1=0+1=1
f(2)=-(2)²+1=-4+1=-3

range={-3,1}
