Step-by-step explanation:
Hey there!
25). Ans;
It is a function. [ many to one function].
26).Ans; Put all values of "x" in (2x^2+7).
a. f(x) = -2
[tex] f( - 2)= 2 \times { (- 2)}^{2} + 7[/tex]
So, f(-2)= 15
b. f(x)= -1.
[tex]f( - 1) = 2 \times ( { - 1)}^{2} + 7[/tex]
So, f(-1)= 9
c. f(x)= 0
[tex]f(0) = 2 \times ( {0)}^{2} + 7[/tex]
So, f(0)= 7
d. f(x)= 1
[tex]f(1) = 2 \times {(1)}^{2} + 7[/tex]
So, f(1)= 9
e. f(x)= 2
[tex]f(2) = 2 \times {(2)}^{2} + 7[/tex]
So, f(2)= 15
f. f(x)= 3.
[tex]f(3) = 2 \times {(3)}^{2} + 7[/tex]
So, f(3)= 25.
Hope it helps...
