Answer:

The initial value of the function is 5

Step-by-step explanation:

we know that

The initial value of the function, is the value of the function when the value of x is equal to zero (the y-intercept)

In this problem

Observing the graph

The y-intercept is the point (05)

therefore

The value of the function for x equal to zero is 5

5t 8=43 whats t.I WILL GIVE 50 POINTS AND IF YOU DONT RECEIVE THE POINTS TELL ME AND I WILL GIVE THEM.PLZ HELP MEEEEEEEEEEEEEEEEEEEEEEE

Answers


==> I can't be sure of the equation.  There's a blank space
        between '5t' and '8', where an operation must be.
       I think the operation is more likely ' + ' (addition).  Brainly usually
       does show the ' - ' if it's subtraction, but goes blank if it's addition.
       Tell you what I'll do:  Since you sound so desperate, and you're being
       so generous with your points,  I'll show you how to figure it out both ways.

----------------------------------------

If it's subtraction:                 5t - 8 = 43

Add  8  to each side:              5t      = 51

Divide each side by  5 :            t     = 51/5

                                                 t     = 10 and 1/5

--------------------------------------------

If it's addition:                         5t + 8  =  43

Subtract  8  from each side:     5t        =  35

Divide each side by  5 :             t        =   7 

t     = 10 and 1/5 i think
