When x = 0 the value of the function is 2 so its either A or B.
When x = 1, y = 8 so substituting these values in A we get:-
8 = 2 * 8^1 = 16 so
its Not A. Try B:-
8 = 2 *4^1 = 8 which fits
Answer is choice B
Step-by-step explanation:
if i pick (3,4) and (6,10)
the formula for gradient is difference in y divided by difference in x . therefore
10-4 divided by 6 - 3 equals to 6 divided by 3 = 2
the gradient is 2
B^5 when you’re dividing exponents, just subtract!
