Find the value of a if the graph of the exponential function y=a.2 passes through the point A(3, 128). Please help I’ll mark brainliest

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^

13cm

step-by-step explanation:

(apex)

oof

step-by-step explanation:

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
