Question

Which of these statements is true for f(x)=4*(7)^x?

Answer 1

Answer:

The Y intercept is (0,4)

Step-by-step explanation:

Answer 2

The y-intercept of function is (0,4)

What is the y-intercept of function?

The y-intercept of function is defined as the point where a curve of function intersect the y-axis of a graph. In other words that find the y value when x equals 0.

What is the exponential function?

An exponential function is defined as a mathematical function represents as the form of f(x) = aˣ.

where x is a variable, and a is a constant called the base of the function.

Given function, f(x) = 4*(7)ˣ that is an exponential function

y = 4*(7)ˣ

To determine the y-intercept substitute the zero in x and solve for y

y = 4*(7)ˣ  

Substitute the value x = 0 in above function,

y = 4*(7)⁰

y = 4*(1)

y = 4

So, the y-intercept of function = (0,4)

Hence, the y-intercept of function is (0,4)
