The given expression is
And log cant gives the value of negative number or 0. THerefore x must be greater then 0. THat is
So the domain is
Range.
To find the range, we have to first find the inverse of the given function. And domain of the inverse function is the range of the given function.
So to find the inverse, first we switch x and y, and then solve for y. That is
And there is no restriction on x. SO the domain of the inverse function is all real numbers. And hence the range of the inverse function is all real numbers.
Correct option is the first option .
Answer:X=3
Step-by-step explanation:We simplify the equation to the form, which is simple to understand
7+x-(3+32/8)=3
Simplifying:
7+x-(3+4)=3
Simplifying terms in parentheses
7+x-(+7)=3
Remove unnecessary parentheses
7+x-7=3
We move all terms containing x to the left and all other terms to the right.
+1x=+3-7+7
We simplify left and right side of the equation.
+1x=+3
We divide both sides of the equation by 1 to get x.
x=3

Answer:
x = 10
Step-by-step explanation:
∵ Both angle ∠A and are corresponding angles.
∠A = ∠B
9x - 40 = 3x + 20
9x = 3x + 20 + 40
9x - 3x = 20 + 40
6x = 60
x = 60/6
x = 10
∴ x = [10]
Answer: 13
Step-by-step explanation:
To get F(x), apply BODMAS; multiply first, then add, finally, subtract
F(x) = 2x4 + 3x3 – 2x2
= 8 + 9 - 4
17-4
f(×)= 13
