find the intercept of

Question

y=4x^2+3

Answer 1

The intercept of which axis?
y can never be less than 3, so the curve never crosses the x axis.
When x = 0 (where it crosses the y axis), y = 3.

Answer 2

so are those the answers for the x and y intercept

Answer 3

yes. Y intercept is when x=0, it is where it crosses the y axis (x is zero).

X intercept is when y is zero, along the x axis. These are commonly used to find roots of equations.
