Suppose
f(x)=−2x^2+x−2
. Compute the following:

A) – 15

B) – 9

Step-by-step explanation:

f(x)=-2x²+x-2

f(-2)= – 2(-2)²+(-2) – 2 = –2(4) –2–2=–8–4=–12

f(1)= – 2(1)²+(1)-2=–2+1–2= – 3

A) f(-2) +f(1)= – 12 + (–3) = – 15

B) f(-2) - f(1)= – 12 - (–3) = – 12 +3= – 9

I hope I helped you^_^

correct answer is b. 27/8

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
