Question

What’s the answer to this math problem?plz answer

Answer 1

Answer: It is B.

Explanation:

A is a quadratic function

B is a linear function because it is a straight line and every input has exactly one output.

C is a is not straight

D failed the vertical line test.

Answer 2

B

Explanation:

Graph B represents a linear function.

Notice that graph D also shows a line, but it is not the graph of a function, since it doesn't pass the vertical line test for functions.

Graph A shows a quadratic function, and graph C shows likely an exponential function. It is graph B the one that is linear, and a function as well.
