please help me with these questions
Answer:
f(1) = - 1
f(-1) = - 2
Step-by-step explanation:
f(1) will lie in the function f(x) = - 2x + 1
Therefore,
f(x) = - 2x + 1
Plug x = 1
f(1) = - 2*1 + 1 = - 2 + 1 = - 1
f(-1) will lie in the function f(x) = - x - 1
Therefore,
f(x) = - x - 1
Plug x = - 1
f(-1) = - 1 - 1 = - 2
Answer:
-1, 0, 1, 11, 3Step-by-step explanation:
Function 1
f(x) = -2x + 1f(1) = -2(1) + 1 = -2 + 1 = -1Function 2
f(x) = -x - 1f(-1) = -(-1) - 1 = 1 - 1 = 0Function 3
f(x) = x + 3f(-2) = -2 + 3 = 1Function 4
f(x) = 2x + 1f(5) = 2(5) + 1 = 11Function 5
f(x) = 3f(6) = 33+(55-111)/25 equals what
Answer:
0.76
Step-by-step explanation:
3+(55-111)/25
=3+(-56)/25
=3+ (-2.24)
=0.76
Answer:
3+(55-111)/25= 0.76
Step-by-step explanation:
Using PEMDAS, you solve 55-111 which is -56
Then you divide -56 by 25 because it is the fourth step, you get -2.24
Add three to -2.24 to get 0.76
If you round UP to the nearest tenth, it will be 0.80

Evaluate the integral using integration by parts with the indicated choices of u and dv. (Use C for the constant of integration.) xe9x dx; u
Answer:
The answer is "[tex]\bold{\frac{ \ e^{9x}}{9} (x-1)+C}\\[/tex]"
Step-by-step explanation:
Taking the integral [tex]\int x^{2x} \ dx[/tex]
Evaluating the integral by using integration:
[tex]u=x\\\\dv=e^{9x} \ dx[/tex]
Let
[tex]u=x\\\\ dv=e^{9x} dx[/tex]
Then,
[tex]\to \frac{du}{dx}= 1 \ and\ v =\int e^{9X} \ dx \\\\\to du = 1 \ dx \\\\\to v = \frac{e^{9x}}{9}\\\\\text{integrate the above value}:\\\\\int\ u \ dv = uv - \int v du \\\\Now, \\\\\to \int x e^{9X} \ dx = x \frac{e^{9x}}{9} - \int \frac{e^{9x}}{9} dx[/tex]
[tex]= \frac{ x \ e^{9x}}{9} - \frac{e^{9x}}{9}\\\\= \frac{ \ e^{9x}}{9} (x-1)+C\\[/tex]
Answer:
[tex]\displaystyle \int {xe^{9x}} \, dx = e^{9x} \bigg( \frac{x}{9} - \frac{1}{81} \bigg) + C[/tex]
