answer will be (B) {R}/5
@7paradoxgamer
@7paradoxgamer 2 года назад
At 20:07 I think answer is correct because hame underroot se kabhi bhi negative value nahi milegi aur y kabhi negative nahi hoga so answer is [0,3]

Kyu for x=0 you will get +-3 na ! Then ??

​@@sakshigupta8324 chatgpt reply -The function you provided is a semicircle equation centered at the origin with a radius of 3. The range of this function represents the set of all possible y-values it can take. To determine the range, we need to find the minimum and maximum values of y for the given function. Since the function represents a semicircle, the y-values will range from the lowest point on the semicircle to the highest point. The lowest point occurs at the bottom of the semicircle, where x = 0. Plugging x = 0 into the equation, we get: y = √(9 - 0^2) = √9 = 3. So, the lowest y-value is 3. The highest point on the semicircle occurs at the top, where the x-coordinate is either 3 or -3. Plugging these values into the equation, we get: For x = 3: y = √(9 - 3^2) = √(9 - 9) = √0 = 0. For x = -3: y = √(9 - (-3)^2) = √(9 - 9) = √0 = 0. Therefore, the highest y-value is 0. Hence, the range of the function y = √(9 - x^2) is [0, 3]. aur waise bhi y=+√9-x2 hai toh y ki negative value consider nahi karenge

in Q no.2 based ondomain and range there is a error in the solution for finding range, when you were applying quadratic formula , instead of 2 we have to write 2y in the denominater and the final answer of range is [ -1/2 to 1/2] -{0}.

B Sir, there is a slight correction in the last question the range of the function sqrt(9-x^2) would be [0,3] since the domain is [-3,3] therefore, on putting the extreme values the results is zero and on the minimal value that is 0 in domain the range will have the maximum value as 3
@instabecreative0507
@instabecreative0507 3 месяца назад
Yes the range will be [0,3] because of the square root function @aniketsatpathy1532 Sir must have changed this by mistake.
