a=4 and b = 0
Step-by-step explanation:
Given : 
To find, The value of a and b
Solution,
Solving LHS of the given equation,

Since,

So,

or

On comparing we get :
a = 4 and b = 0
The values of the functions are -1/ 4, 3/ 16 and 3/ 8 respectively.
<h3>What is a function?</h3>
A function is a rule or expression showing the relationship between a dependent and independent variable.
We have the function to be;
f(x) = 3/ 4(x + 2)
Let's find f(-5), substitute the value of x as -5
f(-5) = 3/ 4 ( -5 + 2)
f(-5) = 3/ 4 × -3
f(-5) = -1/ 4
f(2), substitute the value of x as 2
f(2) = 3/ 4(2 + 2)
f(2) = 3/ 4 (4)
f(2) = 3/ 16
f(4) = 3/ 4 ( 4 + 2)
f(4) = 3/ 4(6)
f(4) = 3/ 8
Thus, the values of the functions are -1/ 4, 3/ 16 and 3/ 8 respectively.

Answer:
12
Step by Step Explanation:
f(n+1) = 2f(n) + 10
a = 2, k = 10
a + k = 2 + 10 = 12
Answer:
4.243
step by step explanation:
<span>To calculate the percentage increase: First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100.
1520-950=570
570÷950= 0.6 × 100=60%
