## If x is a subset of Y then, is inverse of x also a subset of Y?

Let $ f : X \rightarrow Y $ be a function. If B is subset of y then its inverse image $ f^-B $ is the subset of x define by $ f^-B = {x : f(x) \in B} $ Now prove the following. $ i. B_1 \subset B_2 \Rightarrow f^-B_1 \subset f^- B_1 $ […]

## If x belongs to the domain then does f(x) belong to the range?

Let $ F : x \Rightarrow y $ be a function. Then prove that $i. A_1 \subset A_2 \Rightarrow F(A_1) \subset F(A_2)$ $ii. F(\cup_i A_i) = \cup_i F(A_i) $ $iii.F(\cap_i A_i) \subset \cap_i f(A_i)$ Solution $ Let \ f: x \rightarrow y $ be a function. i. $Let\ y \in f(A_1)$ $Then\ \exists x \in […]

## Is the empty set a subspace of every vector space? Justify

Question: a. Is the empty set a subspace of every vector space ? Justify and let s = ${(a, b, (a + b):a, b \in R)}$ . Is a subspace of $R^3$ under the usual operation. Question: b. Let I = (-a , a) a > 0 be an open interval in R let v […]

## Corn Leaf Infection Detection: Data Preprocessing and Custom Datagenerator

Corn Leaf Infection Detection: Data Pre-processing and Custom Datagenerator Introduction Here on this blog, I will be giving a gentle introduction about how to do Region Based Detection project on python from scratch. The scratch means from image capturing to the model release. We have seen lots of computer vision progress but most of them […]
