Answer: 2
Step-by-step explanation:
To get the y-intercept, we put x= 0
and then solve for y in the equation given
y = 2(4^x)
putting x =0
y = 2(4^0)
according to the rule of indices,any variable raise to the power of zero is 1
so 4^0 = 1
y=2(1)
y =2
Therefore y- intercept is 2
Answer:
4/5
0.35 + 0.2 + 0.25 = 0.80
x ≥ - 1
the solid circle above - 1 on the number line indicates that x can equal - 1
the arrow points right indicating x is greater than or equal to - 1 , that is
10 mm = 1 cm
4 mm = 4/10 cm
=0.4 cm
