Question

Please help! Thank you!
Evaluate f(2), f(-3,2), and f(a)
f(t) = -16t(to the second power) + 7.8t + 12

Answer 1

what is
f(-3,2) ??

Answer 2

Sorry! I meant -3.2.

Answer 3

I see ;)

Answer 4

for the first one we insert t=2:
\[f(t) = -16(2)^2 + 7.8\times(2) + 12\]Because exponents have a higher priority than multiplication, the (2) must first be squared before being multiplied with 16

Answer 5

we have three parts of the equation here, separated by +

can you calculate the value for the first part?

Answer 6

-91.6

Answer 7

-16(2)^2 = -91.6 ?
