Question

(Q4) Which values of a and b in the exponential function y = a (bx) would result in the following graph?

Answer 1

Answer: second option.

Step-by-step explanation:

By definition, you know that:

$b^0=1$

You can see in the graph that the interception with the y-axis is at -1.

Therefore, in that point: x=0 and y=-2

Substitute into the function and solve for a:

$-1=a(b)^0\\-1=a(1)\\a=-1$

Now, choose any point of the function and substitute this point and the value of a into the function and solve for b. Then you obtain:

Point (2,-4)

$-4=-1(b)^2\\\frac{-4}{-1}=b^2\\b=\sqrt{4}\\b=2$

Answer 2

Answer:

Its B

Step-by-step explanation:

Because it is
