Answer:
Step-by-step explanation:
Given the exponential function as
substitute both points in the equation above
point (-3,16) will be
point (-1,4) will be
make a the subject of the formula in both equations above
This means
Cross multiply as;
Divide by 4 both sides to get
Divide by b^-1 both sides
Find value of a
Hence
a=2 and b=1/2 thus write the equation as;
