Find f(-5) if f(x) = |x + 1|.

5
4
6

B) 4

Step-by-step explanation:

Solve the Function Operation

f (−5)  f (x) = |x + 1|

Replace the variable x with −5 in the expression.

f (−5) = |(−5) + 1|

Simplify |(−5) + 1|.

Remove parentheses.

|(−5) + 1|

Add −5 and 1.

|−4|

The absolute value is the distance between a number and zero. The distance between −4 and 0 is 4

4

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
