Step-by-step explanation:
[tex]f(x) = 4 {x}^{2} + 5 + {2}^{x} [/tex]
To find f(-4) replace every x in f(x) by - 4
That's
[tex]f( - 4) = 4( { - 4})^{2} + 5 + {2}^{ - 4} \\ \\ = 4(16) + 5 + \frac{1}{16} \\ \\ = 64 + 5 + \frac{1}{16} \\ \\ = 69 + \frac{1}{16} \\ \\ = \frac{1105}{16} \\ \\ = 69 \ \frac{1}{16} [/tex]
Hope this helps you
