Which is a possible turning point for the continuous function f(x)?

a. (–3, –4)
b. (–2, –1)
c. (0, –5)
d. (1, –8)

Answer 1

b (-1, -2) because the function value changed from increasing to decreasing

Answer 2

turning point is (-2,-1)

Explanation:

To find the possible turning point we look at the y values that is f(x) values

The value of f(x) is increasing from

-6 to -4 to -1

After -1 the f(x) is decreasing

-1 to -5, then -5 to -8 and then -8 to -16

This means f(x) is increasing till -1 and then starts decreasing

So turning point is (-2,-1)
