Given f(x) = 19x + 12 , find f(3)
F(3)= ?

69

Step-by-step explanation:

to find f(3), we'll have to substitute x with 3

therefore,

f(3) = 19 × 3 + 12

= 57 + 12

= 69

f ( 3 ) = 69

Step-by-step explanation:

Given :-

f ( x ) = 19x + 12.

To find :- f ( 3 ) = ?

Solution :-

f ( x ) = 19x + 12.

Substitute as the 3 as x

f ( 3 ) = 19 ( 3 ) + 12

Multiply ; 19 × 3

f ( 3 ) = 57 + 12

Add 57 and 12

f ( 3 ) = 69

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
