Question

What facts are true for the graph of the function listed below? Please check all that apply.

F(x)=2 x 5^x

Answer 1

Answer:

E, B, A,

Step-by-step explanation:

C is wrong because it isn't decreasing

D is wrong because if X=0 the 5 to the power of zero would be 1 and 2*1= 2 meaning y goes lower than 5

F is wrong because  if X=0 the 5 to the power of zero would be 1 and 2*1= 2 meaning the y intercept is 2 not 5

Answer 2

Answer:

$\Large \boxed{\mathrm{A , \ B, \ and \ E}}$

Step-by-step explanation:

$F(x)=2 \cdot 5^x$

There are no restrictions on x. The domain is all real numbers.

To find the y-intercept, we set the x value to 0. The y-intercept of the function is (0, 2).

The function is increasing, because as the value of the input increases, the value of the output increases as well.
