Question

Evaluate ƒ(x) when x = -10

A. 16
B. No solution
C. -7
D. -24

Answer 1

B

Explanation:

This is a piecewise function with given intervals

- 3 < x > 10 then f(x) = 2x - 4

10 ≤ x < 3 then f(x) = x² + 3

x = - 10 is not in either of the 2 valid intervals, hence

f(- 10 ) has no solution → B
