Question

What is the range of the function f(x) = –2(6x) + 3?

Answer 1

B is the answer to this question.....

Answer 2

Answer:

The range of the function is (-∞,3)

B is correct.

Step-by-step explanation:

Given: $f(x)=-2(6)^x+3$

It is an exponential function which coefficient is negative.

Exponential function: $f(x)=ab^x+c$

If a>0 then range (c,∞)

If a<0 then range (-∞,c)

$-2(6)^x+3\rightarrow ab^x+c$

$a=-2$

$c=3$

Range: (-∞,3)

Hence, The range of the function is (-∞,3)
