Question

What is the y intercept of the function f(x)=2*5^x+4 please leave an explanation options- 2 4 6 14

Answer 1

y intercept is 6

Explanation:

Given:

`f(x) = 2(5^x) + 4`

Required:

Determine the y intercept

To do this, we simply set x to 0

Substitute 0 for x in
`f(x) = 2(5^x) + 4`

`f(0) = 2(5^0) + 4`

Evaluate the exponent,
`5^0`

`f(0) = 2(1) + 4`

Open bracket

`f(0) = 2 + 4`

`f(0) = 6`

Hence, the y intercept is 6
