Q. Use the following function rule to find f(a−7). Simplify your answer.f(x)=−2xf(a−7)=______
Substitute in function: We are given the function f(x)=−2x and we need to find f(a−7). To do this, we substitute (a−7) for x in the function rule.f(a−7)=−2(a−7)
Distribute −2: Now we distribute the −2 to both terms inside the parentheses.f(a−7)=−2×a+2×7
Simplify expression: Simplify the expression by multiplying −2 with a and 7.f(a−7)=−2a+14
