TR = 6
QR = 2(TR)
QR = 2(6)
QR = 12
-4(8-(-3))+7
Remove the parentheses, negative with negative will equal a positive so the new equation will be -4(8+3)+7. So 8+3=11, -4(11)+7. -4(11)=-44 and then add -44+7 which will equal -37
Answer:
F(x)=2x^2
Step-by-step explanation:
Basically, a quadratic function has x^2 in it (standard form ax^2+bx+c with non-zero a). The others have x^3, -x, x^4, etc., which clearly are NOT x^2.
You just find the quartiles which are 62 and 50 the mines them which equals 12.
