Answer:

D : One Real Root

Step-by-step explanation:

Isolate "4x" by subtracting 7 from both sides.

So we get

4x = -7

Then we divide each side by 4 to get -7/4

x = -7/4 so there is only one real root.

In general, the intercept of the function F(X) = a•b^x is the point

Murljashka [212]

Answer:

$(0,a)$

Step-by-step explanation:

Given

$f(x) = ab^x$

Required

Determine the intercept

The intercept is at point: $x = 0$

So, we have:

$f(0) = ab^0$

$f(0) = a*1$

$f(0) = a$

So, the intercept is at point $(0,a)$

None of the options is true

You have to begin by declaring what g(f(x)) means. It means that wherever you see an x in g(x) you put in f(x).

It will look like this to start with
g(f(x)) = (f(x) + 5) / (f(x)

Now substitute into this for g(-3)

g(x^2 + 5) = (x^2 + 5 + 5)/(x^2 + 5) It's time to use some numbers.
g(- 3) = ((-3)^2 + 10)/( (-3)^2 +5)
g(-3) = ( 9 + 10 ) / ( 9 + 5)
g(-3) = (19)/14 <<<<<< answer.
C <<<< answer.
