Answer:

A. h^2+9h+23

Step-by-step explanation:

F(x) = x^2 +3x + 5.

For f( 3+h), put x = 3+h.

F( 3+h)= (3+h) ^2 + 3 (3+h) +5 = 9 +h^2 + 6h + 9 + 3h + 5 = h^2 + 9h + 23.

Which is an equation of the line that passes through the points (-1,9) and (4, 24)?

choli [55]

Answer:

y = 3x + 12

Step-by-step explanation:

Slope (m) = 24-9/4-(-1)

= 25/5

= 3

Using point (-1 , 9)

y - y1 = m (x - x1)

y - 9 = 3 (x - -1)

y - 9 = 3 (x + 1)

y - 9 = 3x + 3

y = 3x + 3 + 9

y = 3x + 12
