Question

if f(x) is real function on [-1,1],then the function g(x)=f(5x+4). Find the interval of g(x)

Answer 1

Answer:

[-1, 9]

Step-by-step explanation:

g(x) deends on the values of f(5x+4)

To finder thee interval, upper and lower limits of g(x), substitute the upper and lower values of f(x).

lower limit:

g(-1) = 5(-1) + 4 = -1

g(1) = 5(1) + 4 = 9

[-1,9]
