Question

What is the value of a for the exponential function in the
graph represented in the form of f(x) = a(b)?
O -4
O -3
O 3
O 4

Answer 1

Answer:

Option (4)

Step-by-step explanation:

If the given exponential function is in the form of f(x) = $a(b)^x$

From the graph we find that two points (0, 3) and (0.5, 6) lie on the graph.

For (0, 3),

f(0) = $a(b)^0$

3 = a

For (0.5, 6),

f(0.5) = $3(b)^{0.5}$

6 = $3\sqrt{b}$

$\sqrt{b}=2$

b = 4

Therefore, value of b in the given function 'f' is 4.

Option (4) will be the answer.
