F(x)= sqrt of 5x+7 and g(x)= the sqrt of 5x-7

ki77a [65]

F(x) = √(5x + 7)

g(x) = √(5x - 7)

(f + g)(x) = f(x) + g(x)

(f + g)(x) = √(5x + 7) + √(5x - 7)

Use quadratic regression to find

Rashid [163]

The quadratic equation is given by:

y = 3x² + 10x - 8

The standard equation of a parabola is given by:

y = ax² + bx + c

Where a, b, c are constants

At point (4, 80):

80 = a(4)² + b(4) + c

16a + 4b + c = 80 (1)

At point (-3, -11):

-11 = a(-3)² + b(-3) + c

9a - 3b + c = -11 (2)

At point (-1, -15):

-15 = a(-1)² + b(-1) + c

a - b + c = -15 (3)

Solving equations 1, 2 and 3 simultaneously gives:

a = 3, b = 10, c = -8

Therefore the quadratic equation becomes:

y = 3x² + 10x - 8
