F(x) = 4x3 - 5x2 + 7x – 8 and g(x) = 9x – 7. Find (f +9)(x).

Use ^ for representing power values.

Eg: Write input x2 as x^2.

2. Use ^(1/2) for square root ,'*' for multiplication, '/' for division, '+' for addition, '-' for subtraction.

Eg:1. Write input √x as x^(1/2)

2. Write 5x as 5*x.

3. Write x+5 as x+5.

4. Write x2-5x as x^2-5*x.

3. Use paranthesis() while performing arithmetic operations.

Eg:1. Write sinx+cosx+tanx as sin(x)+cos(x)+tan(x)

2. Write secx*tanx as sec(x)*tan(x)

3. Write tanx/sinx as tan(x)/sin(x)

4. Use inv to specify inverse and ln to specify natural log respectively

Eg:1. Write sin-1x as asin(x)

2. Write ln x as ln(x)

5. Sample Inputs for Practice.

Eg:1. Write (10x+2)+(x2) as 10*x+2+x^2.

2. Write cos(x3) as cos(x^3).

3. Write ex+lnx as e^x+ln(x).

Step-by-step explanation:

eww xbox also eww dayz

step-by-step explanation:

just for that im not answering

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
