Find the y intercept.

y = - (2^x)

Hello!

To find the y-intercept of any given equation, you will need to substitute x for zero.

Also, to write the y-intercept as an ordered pair, it will look like (0, y), where y is the y-intercept, and x-value is zero because we substituted zero into all the x-values of the equation.

y = - (2^x) (substitute x = 0)

y = - (2^0) (any exponent raised to the power of zero is equal to one)

y = - (1) (simplify)

y = - 1

Therefore, the y-intercept of the function y, is (0, - 1).
