a = 2, b = 4

Step-by-step explanation:

The equation of a parabola in standard form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is the coefficient of the x² term.

Here (h, k ) = (- 1, 3 ) and coefficient of x² term = 1 , then

y = (x - (- 1))² + 3 , that is

y = (x + 1)² + 3 ← expand factor using FOIL

y = x² + 2x + 1 + 3

y = x² + 2x + 4 ← in standard form

compare to y = x² + ax + b

with a = 2 and b = 4

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29
