Plz ! 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)

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

idk

step-by-step explanation:

its 50 miles away from the starting point
