(q6) decide if the function is an exponential function. if it is, state the initial value and the base. y= -4.8·4^x

D

Step-by-step explanation:

Exponential equation takes the form    where

The equation given in the problem can be written as  , so it is an exponential equation,  where a = -4.8 and b = 4.

Thus we can say that the initial value = -4.8 and the base is 4

The correct answer is  D

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
