Here we use the equation

y = a(b)^x

Taking points (0,4), (1,2)

Substituting the point (0,4) , we will get

4 = a(b)^0
\\
4 = a(1)  \\
a =4

Substituting (1,2) we will get

2 = 4 (b)^1
\\
2/4 = b
\\
b = 1/2

So we have

a = 4, b = 1/2

Therefore , required equation is

y = 4(1/2)^x

Determine the x intercepts of the piecewise function in the image that I sent.
Amanda [17]

To find the x intercept of the function, we would find g(x) = 0

To do this, we would set each expression in the piecewise function to zero and solve for x. We have

For

x/3 + 2 = 0

let us multiply both sides of the equation by 3. We have

x/3 * 3 + 2 * 3 = 0 * 3

x + 6 = 0

x = - 6

- 6 is less than - 1

- 6 < - 1

It satisfies the inequality. Thus, x = - 6 is in the domain

For

4x - 2 = 0

adding 2 to both sides of the equation, we have

4x - 2 + 2 = 0 + 2

4x = 2

Dividing both sides of the equation by 4, we have

4x/4 = 2/4

x = 1/2

x = 1/2 is less than 1. It is not in the domain of this equation. Thus, there is no x interscept at x = 1/2

Therefore, the x intercept of the piecewise function is (- 6, 0)
