Given: 2x^2+3x-5, g(x)=x+9. Find: (fg)(3)
Svetradugi [14.3K]

Answer:

264

Step-by-step explanation:

f(x)=2x^2+3x-5

g(x)=x+9

(fg)(x)=f(x) \times g(x)

\implies (fg)(x)=(2x^2+3x-5)(x+9)

(fg)(3)=(2(3)^2+3(3)-5)(3+9)

\implies (fg)(3)=22 \times 12

\implies (fg)(3)=264

Write the slope-intercept form of the line that passes through (1, -2) and is parallel to the line y = 4x + 2.
Naily [24]

Use

y-y1=m(x-x1)

y-(-2)=4(x-1) Now why 4??Because parallel lines have the exact same slope

y+2=4x-4

y=4x-4-2

y=4x-6

Hope it helps!
