Question

3. This is the graph of f(x) = 2 *(0.7)^x What is the point on the graph when x=1

Answer 1

The point on the graph when x = 1 is (1, 1.4).

Explanation:

To find the point on the graph when x = 1, substitute x = 1 into the given function.

`\begin{aligned}x=1 \implies f(1)&=2 \cdot (0.7)^1\\&=2 \cdot 0.7\\&=1.4 \end{aligned}`

Therefore, the point on the graph when x = 1 is (1, 1.4).
