Question 8 of 25 2 Points
Which of these statements is true for f(x) = 4×(7)^x?
A. It is always decreasing
O B. The y-intercept is (0, 1).
O C. The domain of f(x) is x > 0.
D. The y-intercept is (0,4).
SUBMIT

the y-intercept is (0,4)

Step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
