What is the y-intercept of the exponential function? f(x)=−0.25(6)^x+2−1 enter your answer in the box.

y - intercept when x = 0

so when x = 0,

y  = - 0.25 (6^2) - 1

y = -0.25 (36) - 1

y = -9 - 1

y  = -10

Answer

y intercept= (0 , -10)

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
