Repede sub 1 va rog repedeeee

Answer 1

Răspuns:

Explicație pas cu pas:

f(x) = 2x + 3

f(2) = 2*2 + 3 = 4 + 3 = 7

_______________

E(2; 5)

abscisa = 2

_______________

f(x) = ax + 2

A(4; 6)

a*4 + 2 = 6

a*4 = 6 - 2 = 4

a = 4: 4 = 1

________________

f(x) = 4x + b

B(2; 10)

4*2 +b = 10

8 + b = 10

b = 10 - 8 = 2

__________________

f(x) = 3x + 2

C(c; 11)

3c + 2 = 11

3c = 11 - 2 = 9

c = 9 : 3 = 3

________________

D(3; -1)

f(3) = -1

_______________

f(x) = 5x + 3

f(x) = 8

5x + 3 = 8

5x = 8 - 3 = 5

x = 5 : 5 = 1
