HELP !!! Evaluate f(-2) for the function f(x) = 3x2 + 2x - 5
Phoenix [80]

Answer:

3

Step-by-step explanation:

So we have the function:

f(x)=3x^2+2x-5

To evaluate the value of f(-2), substitute -2 for x. Thus:

f(-2)=3(-2)^2+2(-2)-5

Square first:

f(-2)=3(4)+2(-2)-5

Multiply:

f(-2)=12-4-5

Now, subtract:

f(-2)=8-5=3

So:

f(-2)=3

And we're done!

Solve the equation by using quadratic formula . Show your work! Answer maybe in radical or decimal form .
Lorico [155]

Answer:

x_1=\frac{-2+\sqrt{14}}{2}\approx 0.871,x_2=\frac{-2-\sqrt{14}}{2}\approx-2.871

Step-by-step explanation:

2x^2+4x-5=0

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

x=\frac{-4\pm\sqrt{4^2-4(2)(-5)}}{2(2)}

x=\frac{-4\pm\sqrt{16+40}}{4}

x=\frac{-4\pm\sqrt{56}}{4}

x=\frac{-4\pm2\sqrt{14}}{4}

x=\frac{-2\pm\sqrt{14}}{2}

x_1=\frac{-2+\sqrt{14}}{2}\approx 0.871,x_2=\frac{-2-\sqrt{14}}{2}\approx-2.871
