Which function is represented by the graph? O f(x) = -2[x] + 1
O f(x) = -21X1+1
O f(x) = -2|x + 11
O AX) = = {\x + 1]

HURRY PLEASE !!!

f(x) = −|x + 4| + 3

Step-by-step explanation:

since, the value of the function at x=0 is -1

so, we will check which functions gives the same value

f(x) = −|x − 3| + 4  at x=0 it gives 1

f(x) = −|x + 3| + 4  at x=0 it also gives 1

f(x) = −|x − 4| + 3   at x=0 it gives -1

f(x) = −|x + 4| + 3   at x=0 it also gives -1

so, we have discarded first two options

Now at x=4 function gives negative value

f(x) = −|x − 4| + 3   at x=4 it gives 3

f(x) = −|x + 4| + 3 whereas at x=4 it gives -5

Hence, the function  represented by the graph is:

f(x) = −|x + 4| + 3

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
