Students graphed the growth rate over several weeks of two plants in their classroom. The equations of both plants
are given where x represents the time in weeks and y represents the heights of the plants in inches.
Plant A. y = 1.8x + 3.1
Plant B y = 2.3x + 1.9
Approximately how many weeks will it take for both plants to reach the same height? Round your answer to the
nearest tenth
O 1.9 weeks
2.4 weeks
O 3.1 weeks
O 7.4 weeks

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars

i believe it's a.

i'm not sure on this one, most likely correct.

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
