How do you solve 2cos^2(x) + sin(x) - 2 = 0 over the interval from 0 to 2pi? Use the function f(x) = x^2 - 4 and g(x) = 2x + 20. Solve f(x) \geq 1, what is the correct answer in interval notation? Solve the equation graphically in the given interval: 2...
Interval Notation: (-∞,1)∪(1,∞) Use each root to create test intervals. $$ x \leq - 3 $$ $$ - 3 1 $$ Choose a test value from each interval and pl ug this value into the original inequality to de termine which intervals satisfy the inequality. x1True T he solution consi...
1) **x ≤ 3**:所有小于或等于3的实数。左端为负无穷(开口),右端包含3(闭合),区间为(-∞, 3]。2) **-2 < x ≤4**:x严格大于-2但不超过4。左端开口(不包含-2),右端闭合(包含4),区间为(-2, 4]。3) **-9 ≤x ≤0**:两端均闭合(包含-9和0),区间为[-9, 0]。
