PLZ HELP ME!!!!!
Find the y-intercept of the following equations.
y=3^x
y=0.25^x
y=-(2^x)
y=2(0.3)^x
y=2^x-3 (-3 is not part of the exponent)
y=4(0.5)^x+5 (-5 is not part of the exponent)

Respuesta :

Answer:

1. (0, 1)


Step-by-step explanation:

Put x = 0 then work out the values of y:0

y = 3^0 = 1  y-intercept is (0,1)

y = 0,25^x , y = 0.25^0 = 1

All the others are done in same way
