Answer with explanation:

The given function is

$y=7^{4x}$

Domain of the function is defined as set of all values of x for which y is defined.

In the given function ,y is defined for all real values of x.

So, Domain of the function =R--Set of real numbers.

Range of the function is defined as set of all values of y, for which x is defined.

$y=7^{4x}\\\\ \text{Taking log on both sides}\\\\ \log y=4x \log 7\\\\x=\frac{\log y}{4 \log 7}$

⇒log y is defined for, y>0.

Range of the function will be

=(0,∞)

=Set of Positive real numbers

for triangular part:base=8in, height=3in

area of the given fig:

area of the given fig:area of 2 triangles +area of rectangle 

 $→2( \frac{1}{2} \times b \times h) + l \times b \\ →2( \frac{1}{2} \times 8 \times 3) + 12 \times 8 \\ →24 + 96 \\ → {120in}^{2}$

5/6 = 1/3+d and x/x is a fraction

Alik [6]

$\dfrac{1}{3}+d=\dfrac{5}{6}\qquad|-\dfrac{1}{3}\\\\d=\dfrac{5}{6}-\dfrac{1}{3}\\\\d=\dfrac{5}{6}-\dfrac{1\cdot2}{3\cdot2}\\\\d=\dfrac{5}{6}-\dfrac{2}{6}\\\\d=\dfrac{5-2}{6}\\\\d=\dfrac{3}{6}\\\\d=\dfrac{3:3}{6:3}\\\\\boxed{d=\dfrac{1}{2}}$
