#2: This function is not defined if the denominator = 0. So, steal the denom. and set it = to 0, and then solve the resulting eqn: 3x-1=0, 3x = 1, x = 1/3.
The domain is the set of all real numbers except for x = 1/3. The range is the set of all real numbers except for y = 0.
#4: this function will not be defined if 16-x^4 is less than 0.
so you must solve the inequality x^4 ≤ 16. Take the 4th root of both sides. The domain is (-2, 2). By all means, check. Suppose x = 1.5. is x^4≤16?
The smallest value y can have is zero, which occurs when x = plus or minus 2.

<em><u>The surface area of cylinder in standard form is:</u></em>
<em><u>Solution:</u></em>
Given that,
Radius of cylinder = 2x + 3 inches
Height of cylinder = 3 times radius = 3(2x + 3)
Height of cylinder = 6x + 9 inches
<em><u>The surface area of cylinder is given by formula:</u></em>
Where, "r" is the radius and "h" is the height of cylinder
<em><u>Substituting the given values we get,</u></em>
Thus the surface area of cylinder in standard form is found
Answer:
Step-by-step explanation:
4. 2x+8+3x+5=123 (ext∠)
5x=110
x=22
5. 25+2x+3=3x-17 (ext∠)
x= 45
6. 5x+2+6x+4=12x-4 (ext∠)
x= 10
