Answer:

Below in bold.

Step-by-step explanation:

x can have any real value - the domain is (-∞, ∞).

f(x) cannot be 0 or negative, no matter how negative x is, - the range is (0, ∞)

Answer:

Domain: all real values of x

Range: f(x) > 0

Step-by-step explanation:

f(x) = 3^x

There's no domain restriction, so x can take any real value

Tye graph f(x) has a horizontal asymptote at y = 0 because with a positive base, the output can never be 0 or negative

Hence the range is y > 0

Answer:

Step-by-step explanation:

Given

$\frac{5x^2+8x+7}{4x}$

Divide each term on the numerator by 4x

= $\frac{5x^2}{4x}$ + $\frac{8x}{4x}$ + $\frac{7}{4x}$

= $\frac{5x}{4}$ + 2 + $\frac{7}{4x}$
