Question

True or False
a function may assign more than one output value to one of its input values

Answer 1

a, b, c, and d

Answer 2

lier D. is a circle

Answer 3

it's the function of a line which is a circle
were you only after a particular type of function...?

Answer 4

yes but is doesnt pass the vertical line test

Answer 5

Di is a circle and is not a function

Answer 6

A fails the verticle line test (its looks like a x pattern)

Answer 7

B is a line and C is parabola, both are functions

Answer 8

same thing wont pass the vertical line test it touches twice

Answer 9

this is what it looks like if you plot it... hyperbolic function or something similar
x^2 + y^2 =1 is function of a circle, my bad

Answer 10

whats the vertical line test?

Answer 11

True or False
a function may assign more than one output value to one of its input values

Answer 12

@jack1 imagine moving a vertical line left to right, along the x-axis. If the line ever intersects the function more than once, it's not a function.

Answer 13

imagine a line parallel to to the y-axis, a function only passes that line once throughout its range

Answer 14

so ur telling me parabolas aren't functions...?
cubics?
quadratics? @agent0smith

Answer 15

they are

Answer 16

Would a vertical line intersect a vertical parabola more than once?

Answer 17

if it was a horizontal parabola it certainly would

Answer 18

Thus a horizontal parabola is not a function.
