For each function shown: •name that starting point
•explain how y changes as x increases
function#1: y=0.5+3x
function#2: y=3(0.5)x

Step-by-step explanation:

Function (1) has been given as,

y = 0.5 + 3x

Table for the points on this function,

x        0         1          2          3         4

y       0.5     3.5       6.5      9.5     12.5

There is a common difference of 3 each successive term of y from the previous term.

Therefore, starting point of the function is (0, 0.5)

There is a linear growth of 3 with the increase in the value of x.

Function (2),

y = 3(0.5)ˣ

x       0         1          2           3           4

y       3        1.5     0.75     0.375   0.1875

Starting point of the function will be (0, 3)

There is a common ratio of 0.5 in each successive term to the previous term.

Function (2) increases exponentially with a common ratio of (0.5) with the increase in x.

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
