Answer:

<h2>120</h2>

Step-by-step explanation:

Given,

x = -2

Now, let's solve

{7x}^{4}  + 3 {x}^{2}  - 4

Plug the value of x

= 7 \times  {( - 2)}^{4}  + 3 \times  {( - 2)}^{2}  - 4

A negative base raised to an even power equals a positive

= 7 \times  {2}^{4}  + 3 \times  {2}^{2}  - 4

Evaluate the power

= 7 \times 16 + 3 \times 4 - 4

Multiply the numbers

= 112 + 12 - 4

Add the numbers

= 124 - 4

Subtract the numbers

= 120

Hope this helps ...

Best regards!!

Answer:

c) 120

Step-by-step explanation:

f(x) = 7x^4 + 3x^2 - 4

f(-2) = 7(-2)^4 + 3(-2)^2 - 4 = 7(16) + 3(4) - 4 = 112 + 12 - 4 = 120
