Solution:
we are given that

we have been asked to find f(x).
we can find the value of f(x) by re-writing the given function in the form of f(x+3) and thereafter we will replace (x+3) by x.
we can re-write the given function as below

Hence the expression representing f(x) is f(x)=4x+3.
Answer:
Step-by-step explanation:
1+4x=29
-1 -1
4x=28
4x/4=28/4
X=7
Step-by-step explanation:
since maxima is a point in which a function within a range gives maximum value. And its value is called maximum value of the function over an interval.
The value of r is 26(approximately).
Answer:
BC = 60
Step-by-step explanation:
3X + X = 80 <---- X = BC
3X + X = 4X
4X = 80 <---- DIVIDE BOTH SIDES BY 4
4X ÷ 4 = X
80 ÷ 4 = 20
20 × 3 = 60
