What is the y-intercept of the exponential function?

f(x)=−1/8(4)^x+3+6

ANSWER:

The y – intercept of given exponential function is -2

SOLUTION:

Given, exponential function is

We have to find the y – intercept of the above function.

We know that, y– intercept is the value of y on a point where the given function meets y – axis.

At that point x always be 0. So put x = 0 in f(x).

Hence, the y – intercept of given exponential function is -2

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
