Question

7. Find the range of each function for tff f e given domain f(x) = 2x}; {-1, 0,5}

Answer 1

f(x) = 2x³

D: {-1,0,5}

Evaluate the function for every value:

For x=-1

f(-1) = 2*(-1)³ = 2*(-1) = -2

For x=0

f(0) = 2*(0)³ = 2*(0) = 0

For x=5

f(5) = 2*(5)³ = 2*(125) = 250

Therefore, the range is:

R: {-2,0,250}
