Given the already defined variables is_full_time_student and age, write an expression that evaluates to true if age is less than 19 or is_full_time_student is true.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

i can't read the graph

step-by-step explanation:

thus, the first answer choice, y = sec x, is the correct one
