Answer:

1 - A is not a function

2 - B is not a function

3 - A is not a function

X can have only 1 value

for example 2B features x=5 where f(x) = -4 but also 1. That means it's not a function

How do I solve quadratic equations for example,h(t) = – 0.07t2 + 0.007t + 5

Answer:

x ≈ -8.402, 8.502

Step-by-step explanation:

The usual methods of solving quadratic equations apply to this one. Any of them can be used: graphing, factoring, completing the square, quadratic formula.

<h3>Solution</h3>

Often, when the coefficients are non-integers and have no obvious relationship to each other, the most convenient method of solution is the quadratic formula. It tells you the solution to ax²+bx+c=0 is ...

$x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

Your equation has the coefficients, a = -0.07, b = 0.007, c = 5, so the solutions are ...

$x=\dfrac{-0.007\pm\sqrt{0.007^2-4(-0.07)(5)}}{2(-0.07)}=\dfrac{-0.007\pm\sqrt{1.400049}}{-0.14}\\\\x=0.05\pm\sqrt{\dfrac{200007}{2800}}=0.05\pm\sqrt{71.4310\overline{714285}}\\\\\boxed{x\approx\{-8.40169,\,8.50169\}}$
