What is the nature of the curve?
Options:
- a) A straight line passing through (1, 4)
- b) A straight line passing through (-1, 4)
- c) A parabola with vertex at origin and focus at (2, 0)
- d) A parabola with vertex at origin and focus at (1, 0)
- a) A straight line passing through (1, 4)
- b) A straight line passing through (-1, 4)
- c) A parabola with vertex at origin and focus at (2, 0)
- d) A parabola with vertex at origin and focus at (1, 0)
correct answer : a)
Explanation:
\ dy
dx
= 4 Þ ∫dy = ∫4dx
y = 4x + c
\ it passes through (0, 0) then c = 0
\ y = 4x
Hence it is an equation of a straight line passing
through (1, 4)
