The answer would be B. $387.50
Answer:
Since that is a quadratic equation, it will have 2 "x" intercepts.
x^2+7x+2
a = 1 b = 7 c = 2
You would solve for "x" using the quadratic formula.
x = [ -b +- sq root (b ^ 2 - 4 a c) ] / 2 a
x = [ -7 +- sq root (7^2 - 4*1*2) ] / 2 * 1
x = [ -7 +- sq root (49 -8) ] / 2
x1 = [-7 + 6.4031242] / 2
x1 = -.29844
x2 = [-7 - 6.4031242] / 2
x2 = -6.7016
Step-by-step explanation:
Answer:
= 2
Step-by-step explanation:
# g(x) = x^2 + 3 hence g(-2) = (−2)2+3=4+3=7
and so f(g(-2)) = f(7) = 7 - 5 = 2
