Answer:
63.4
Step-by-step explanation:
The triangle is right angled , so :
tan S = UT/ST
tan S = 2/1
tan S = 2
S = 2
S = 63.4
Plug in x = -1 to get...
f(x) = 2*x^2 - 6
f(x) = 2*(x)^2 - 6
f(-1) = 2*(-1)^2 - 6 ... note how each x is replaced with -1
f(-1) = 2*(1) - 6
f(-1) = 2 - 6
f(-1) = -4
Answer is choice B) -4
Answer:
While it's true that quadratic functions have no domain restrictions, the range is restricted because x2 ≥ 0. The correct answer is: The domain is all real numbers and the range is all real numbers f(x) such that f(x) ≥ 7.
