SOMEONE PLS HELP ASAP!!!

Answer 1

Answer: $h(x)=10(0.4)^x$

Step-by-step explanation:

The exponential function h, represented in the table, can be written as $h(x)=ab^x$

From table, at x=0, h(x) =10

Put theses values in equation,, we get

$10=a.b^0\\\\\Rightarrow\ 10= a (1)\\\\\Rightarrow\ a= 10$

Also, for x= 1 , h(x) = 4, so put these values and a=10 in the equation , we get

$4=10b^1\\\\\Rightarrow\ b=\dfrac{4}{10}\\\\\Rightarrow\ b= 0.4$

Put value of a and b in the equation ,

$h(x)=10(0.4)^x$  →  Required equation.
